Rare Book Highlights: Eclipse!

Do you have plans to watch the eclipse today? I do! As you read this, imagine me already stationed within the path of totality.

If you are experiencing eclipse fever, you may be interested, like I was, to know what books we have in Special Collections related to eclipses. A quick search of the library’s catalog brought back the following book with the subject heading, “Solar eclipses — Mathematics”:

Petrus Elvius. Exercitium mathematicum eclipsiographiam solis leviter adumbrans… Upsaliæ : Literis Wernerianis, 1710. Call number: QB541 E48x 1710.

Checking the shelves I found a small pamphlet bound in blue paper wrappers that have become entirely detached. It is kept in this protective four-flap binder:

The Elvius pamphlet in its four-flap binder. Written on the front cover is “Elvius et Milberg 1710”.

The title page begins with the line, “Auspice DEO!” (Under the auspices of God!). Although this was published early during the Age of Enlightenment, we can surmise that it took some time for the influence of religion on science to recede.

Auspice Deo! Exercitium Mathematicum Eclipsiographiam solis leviter adumbrans, quod consentiente ampliss. Facult. Philos. in Regia Academia Upsaliensi, Praeside viro celberrimo, Mag. Petro Elfvio, Math. Super. Profesi. Reg. & h. t. Fac. Phil. Decano Spectabili, Aequitori Bonorum Censurae modeste submittit

Elvius pamphlet title page.

Written in Latin, the Eclipsographia solis, as it is also known, contains an explanation of the mathematical calculations of eclipses, including their duration. At the beginning, after the dedication, there is this delightful fold-out set of diagrams:

Four black ink diagrams showing various angles across portions of a spear labelled with numbers and letters. One diagram includes a sun with a nose and mouth.

Diagrams in Elvius pamphlet.

What did people know about eclipses, or even the solar system in general, when this pamphlet was published in 1710? People have been awed by–and therefore have studied–the phenomenon of eclipses for millennia. The astronomer Gerald Hawkins contended in the 1960s that Stonehenge was used to predict eclipses. Eclipses were studied by the ancient Babylonian, Chinese, Arabic, and Greek astronomers. Anthony Aveni writes in his book In the Shadow of the Moon, “Beginning about the sixteenth century, eclipse observations of a scientific nature begin to enter historical records on the European continent” (p. 137). In 1543, with the publication of his book De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres), Nicholas Copernicus revolutionized European astronomy by demonstrating mathematically that the Sun, rather than the Earth, was at the center of the universe. Galileo later defended the Copernican system in his 1632 publication Dialogo sopra i due massimi sistemi del mondo (Dialogue Concerning the Two Chief World Systems), which got him in trouble with Pope Urban VIII and led to his house arrest. Johannes Kepler improved on the work of Copernicus with his work on the laws of planetary motion, elucidated in his Astronomia nova (New Astronomy) published in 1609. Isaac Newton in 1687 published his Principia, in which he stated his laws of motion and universal gravitation. He also showed how Kepler’s laws followed the same principles as his law of gravity, proving that the same laws of motion govern objects both on the earth and in space.

It would seem by 1710, when our pamphlet was written, that European astronomers knew quite a bit about the solar system and the movement of the planets. In reality, it took some time for the new ideas about the solar system to be fully accepted. (Remember the “Auspice DEO!” of the title page?) Petrus Elvius, the author of our pamphlet, was a Swedish professor of astronomy at Uppsala University and lived from 1660 to 1718. According to his entry in the Swedish Biographical Dictionary (Svenskt biografiskt lexikon), his position on the Copernican system was not clear, and he expressed doubt over the validity of Newton’s law of universal gravitation in a letter 1711 letter to Emanuel Swedenborg, calling it “abstraction” and not physics.

Interestingly, this book was published 5 years before the May 3, 1715 total solar eclipse that crossed central England and Northern Europe. Edmond Halley, famous for calculating the orbit of the eponymously named Halley’s Comet, predicted the path of the eclipse with a very high degree of accuracy (within 4 minutes) and drew a map of its path across England. This map helped to promote popular interest in eclipse-watching (much like today), and it also set off a period of increasingly accurate eclipse mapping.

Happy eclipse day, everyone!

Domestic Economy Class #TBT

The first day of school is Monday, August 21. We are so excited! The students pictured below seem a little less enthused about being in class. Perhaps the absence of smiles was merely a convention of their time and not a reflection on how they felt about class. This article in Time provides possible reasons why people didn’t smile in earlier photographs.

Archival Research: Managua, Nicaragua versus Ames, Iowa

Today’s blog post was written by Sydney Marshall, one of our student workers and a graduate student here at Iowa State University (ISU).

My name is Sydney Marshall and I am one of the student workers for the Special Collections and University Archives (SCUA) at ISU. During this summer, I traveled abroad to Managua, Nicaragua for archival research at the Instituto de Historia de Nicaragua y Centroamerica (Institute of Nicaraguan and Central American History, IHNCA) at the Universidad de Centroamericana (University of Central America, UCA). My research project concerns women during the Nicaraguan revolutionary era. I found that IHNCA had a vast array of information regarding this time period.

Conducting historical research in both the United States and in Central America, I found that there are some surprising similarities to the research process. For one thing, entering a new archive and introducing yourself to the archivist is somewhat terrifying, no matter the country or language! For any archival research, I found that it is best practice to contact the archivist at the desired location to plan one’s research trip (i.e. Dates, times, materials, questions). The primary difference in this initial phase was that I needed permission from my department of study (ISU) in order to gain access to the archives in Nicaragua. Additionally, at IHNCA I had to pay a one-time fee for entrance into the archives, whereas at SCUA, admission is free.

At both SCUA and IHNCA, I was met with friendly staff that helped me with my research project. Both places required me to sign in and read (SCUA) or listen (IHNCA) to the reading room rules. Personal items were kept at the front desk, either in a locker (SCUA) or cubby (IHNCA). Food and drink were not allowed near the documents, however, water was permitted in the reading room at IHNCA. I used the reading room computer to go online and find the materials I wanted an archivist to retrieve (both links can be found below). Each archive had me complete an “out slip” with my name, date, title, and call number for each individual item (the only difference being that I had to state my research topic each time for IHNCA, which I only had to do once for SCUA).

Once the items were brought out to the reading room, I could look at one document at a time. Whereas SCUA brought out the document box containing the desired folder, IHNCA brought out the single folder for me to examine. At IHNCA, I was allowed to bring my own notebook and/or computer to take notes using pencil. At SCUA, I could only take notes using the archives paper and writing utensil. Laptops or other mobile devices are allowed. If I wanted to take a picture of a document, I needed to obtain permission from the archive. SCUA required me to read and fill out the camera use policy form. There is also a KIC scanner in the SCUA reading room that I can use to make copies. For a fee, IHNCA allowed pictures of books and journals to be taken on a specific day at a certain time.

My conclusion after researching in the two archives is that the process for examining historical documents was very similar: ask for the desired item, read the documents, and take notes on what is deemed important. Each archive had a rich collection of materials, from government documents to published books, photos to individual’s recollections.

Iowa State University at the Iowa State Fair

During the next two weeks, hundreds of thousands of people will converge on Des Moines for the annual spectacle that is the Iowa State Fair. As usual, there will be all kinds of activities and exhibits at the fair, but the main attraction continues to be Iowa’s agricultural enterprises. Considering the prominence of agriculture at the fair, it probably comes as no surprise that Iowa State University has been participating in the State Fair for well over a century–back when the school was known as the Iowa Agricultural College.

State fair display, 1924

In a written account of the 38th annual state fair held in 1891, the exhibit presented by the Iowa Agricultural College highlighted the three departments of entomology, botany, and civil engineering. The purpose of the exhibit was to:

“…acquaint the public with their friends and foes of field and garden, the best methods of preserving and destroying them, the noxious weeds and various diseases of plants, with methods of treatment, and to illustrate some of the work pursued in the college curriculum.” Annual Report of the Board of Directors, Iowa State Agricultural Society, 1891.

Even though members of the college saw the state fair as an opportunity to educate the citizenry about important research going on at the school, it was also clear that they recognized the benefits of advertising at the fair.

Annual Report of the Iowa State Agricutural Society, 1891

Annual Report of the Board of Directors of the Iowa State Agriculture Society, 1891. Starting at the bottom of page 140 is the description of the Iowa Agricultural College exhibit.

By the 1920s, Iowa State’s presence at the fair had expanded greatly. Many departments, even those outside of the field of agriculture, were highlighted in the exhibits. Photographs from that era show exhibits sponsored by engineering, home economics, as well as the traditional agriculture programs. One portion of the 1924 exhibit featured a chemical engineering exhibit next to a promotion for a young college radio service called WOI. In 1930, Iowa State’s exhibit included a display from the women’s physical education program featuring two young women demonstrating ping pong on a rather undersized table–at least by today’s standards. You never know what you will see at the fair!

Over the years, the University’s state fair exhibits became more professional-looking and more elaborate. By the 1990s, the Office of University Marketing took charge of planning Iowa State’s exhibit at the fair. University Marketing staff determine a theme for each year’s exhibit emphasizing different aspects of the University. Sadly, visitors are not likely to see college students giving demonstrations as happened in the past, but they are sure to run into the friendly faces of ISU employees, faculty, alumni, and friends that staff the exhibit.

Just as it was in 1891, the Iowa State Fair is still a great opportunity for the University to advertise itself and to share at least part of the story of Iowa State with the tens of thousands of people from around the country that stop by the exhibit. So when you visit the Varied Industries Building to pick up ISU athletics posters and temporary tattoos at this year’s ISU exhibit, take some time to read and learn about some of the great things currently going on at the University. And, of course, if you are more interested in seeing images of the ISU state fair exhibit from years past, stop by Special Collections and University Archives. We would love to see you!

The results are in: Intaglio class final projects

It is not often that I get to see the results of my Special Collections instruction sessions in such a tangible way.  Back in February, I worked with April Katz’s Intaglio class, who came in to view and take photos of examples of intaglio prints from a variety of our rare books to incorporate into their own studio projects. In April I had the pleasure of attending the class’s final critique and seeing the fruits of their labor.

All of the prints were inspiring and beautiful to see. I am highlighting here a few in which I could clearly decipher where the inspiration came from in our collections.

Here, for example, is the work of Jen Wichers, who took as inspiration images from a book on French fashion from the 1780s (Cornu, Paul, et. al. Galerie des Modes et Costumes Francais. Paris: É. Lévy, 1912?. Call number: GT865 G132).


Anna Wagner was inspired by images of tools from Diderot’s French Enlightenment Encyclopédie (Diderot, Denis. Encyclopédie. Paris: Briasson, etc, 1751-65. Call number: AE25 En185) in these prints of hammers with entwined flowers.

One of our botanical books inspired this work by Alexandria Collins, which shows the interplay of the natural and the man-made. (Hooker, William Jackson. Flora boreali-americana. London: H.G. Bohn, 1840. Call  number: QK201 .H764f)

Here is a final set of photos of the work of Jordan Jorgensen, who was also inspired by Diderot. I like the interplay of the hand tool (scissors) and the larger machine (spinning wheel) and the faceless woman running it.

Thank you to April Katz’s ARTIS 357/557, Intaglio & Monotype class for allowing me to attend your final critique and show off your work on our blog. You did great work!


Building a Video Preservation Rack for In-House Digitization AV CLUB | Issue 1


ISU’s Special Collections and University Archives Video Preservation Rack

Hello! My name is Rosie Rowe, and I’m the AV and Film Preservation Specialist for ISU Special Collections and University Archives. This is the first of – hopefully – a series of blog posts related to AV and film preservation from a University Archives perspective. I hope these will be helpful not only for other Universities’ special collections but also for anyone interested in AV and film preservation.

A Common Video Preservation Scenario: A researcher requests a copy of a show held in your special collections. It’s a university production from the 1970s, a unique recording on ¾” tape. This tape is an “at-risk” item, because the inherent vulnerabilities of magnetic based media. What do you do? Do you send it out to a vendor, or do you digitize the tape in-house? Where possible, it’s best to digitize at-risk items in-house. It’s faster, it’s more economical over the long-term, and you can maintain your own quality-control standards.

AV preservationists have spent un-countable hours of our lives discussing the best capture format for analog video preservation. But actually… how you send the signal from the deck to the computer’s capture card is the most important aspect of digitizing analog video. You can capture 10-bit 4:2:2 anything, but the quality of what you’re capturing is linked to the signal you’re sending. So with this fact in mind, this post will describe the necessary equipment and guide you through the basic setup required for digitizing your at-risk analog video in-house.

One of the biggest issues that defines magnetic media as “at-risk” is obsolescence. It’s quite difficult to find and maintain the device needed for analog video playback. Prepare to spend some time digging around online or contacting potential dealers to find a functioning playback device. A good place to start looking for old, obsolete AV equipment is the on-campus video production house. They might have old gear hanging around! Or a local television station may have gear to donate to your archives. Be creative. You need well-maintained, industry-grade equipment with as much related documentation as possible. Those dog-eared operational and service manuals are invaluable for maintaining the functionality of old gear.

Cable - 3

RG-59/U 75 Ohms Broadcast BNC Video Cable

Using correct cables and cabling may be the single most important aspect to setting up a video preservation rack. Know your source signal (composite, component, or Y/C ) and send it out using only the highest-grade shielded cable. Remember: Shielding reduces electrical noise and…its impact on signals and…lowers electromagnetic radiation. Shielding prevents cross-talk between cables… Shielding not only protects cable but… machinery and people as well. [1] http://www.wireandcabletips.com/importance-shielding-cabling/

PRO-TIPS: Cables, Cabling, and Termination
• ALWAYS use broadcast-quality RG59 BNC 75ohm cables for video
• ALWAYS prefer XLR (balanced audio) cables to RCA (unbalanced audio) cables
• ALWAYS terminate open loops with 75ohm terminators at end of signal loops*

*But be careful! Improper termination can affect the video signal. A double termination can cut the video signal in half, while a lack of termination will overload the video signal. This might be where you need professional help.


BNC 75 Ohms Terminator

CONGRATULATIONS!! You have managed to acquire a professional-grade BVU U-matic deck that supports machine control input. Now you are able to control the deck from a computer via a RS-422 cable, not missing any information at the beginning of the tape. This is good. This is why the RS-422 cable is included on the equipment list.

RS-422 - 2

Deck Control RS-422 cable

Now what about the capture card and computer? I like the AJA KONA LHi capture card and AJA KONA KLHi-Box. Together, these will allow for seamless capture of composite, component, and Y/C (for analog signals) and SDI or HDMI (for digital signals). The KONA LHi works well with Premiere CS6, but it also has its own software that captures SD analog video as 10-bit 4:2:2 uncompressed v210. The Kona LHi is also able to capture closed captioning and timecode information. All of these are required metadata for video preservation. The preservation master could have up to five streams of data per file: a video stream, two audio streams, timecode, and closed captioning CEA-608. With newer computers, you’ll have to place the AJA Kona Li capture card in a thunderbolt expansion case and send the digital video signal from the expansion case to computer‘s thunderbolt in.

Now. It’s very important to place a Time Base Corrector between the deck and the capture card. You also need waveform and vector scope connected post-TBC, so you can monitor and adjust the video signal, using the scopes as your measurement tools. For example, if color bars are in front of the program, you can adjust the luma, chroma, black (set up), and hue (NTSC only) levels to get the best possible signal from the tape. Also, I recommend having all equipment ‘genlocked’ to the same reference to ensure picture stability. For SD composite video, it’s called blackburst – a composite signal of black with no picture data. With all pieces of equipment timed and in-sync, or locked to master sync, you increase the stability of your capture.

My preference for signal monitoring is viewing the signal directly off the deck, as well as post capture card. This helps pinpoint where any problems might occur in the signal. For example, if there is visible signal error on the monitor connected at the end of the chain (post capture), but the video looks good coming straight out of the deck, you can focus your troubleshooting on the cables, settings, and equipment either at or after the TBC point. It’s also important to have a cathode ray tube (CRT) monitor in order to view the video signal as it was originally intended. AND it’s best to have a CRT with blue-only, underscan, and H-V delay features. ‘Blue only’ allows you to calibrate your reference monitor with color bars and monitor your VTR noise. ‘Underscan’ allows you to see every scan line in the video signal, and ‘H-V delay’ allows you to check vertical and horizontal sync. These features will help you get the best signal out of your deck and troubleshoot any signal errors.

This brings me to the last piece of gear to install in your AV Rack: a test pattern generator. A test generator helps you check proper signal flow by sending a test pattern, like color bars, through the signal path. You can also use the color bar test pattern to set display levels – like brightness – and contrast to ensure your monitor is properly calibrated.

Well, I hope this was helpful for anyone wanting to build an AV preservation rack for their special collections. In the next issue of AV Club, I’ll be discussing best practice for embedding technical metadata into files for future digital preservation conservators. Cheers!

Rare Book Highlights: Railroad tourism to Iowa lakes

Nichols, C. S. Spirit Lake and the Okobojis. Steubenville: Burlington, Cedar Rapids & Northern Ry., 1901.

Cover of the pamphlet, Spirit Lake and the Okobojis. Notice the Native American paddling a canoe through reeds in the green below the title.

During the summer, I love to spend time at a lake. Clear Lake in north central Iowa is a favorite of mine because it is the closest natural lake to where I live in Iowa. People have been leaving the heated cities behind to spend summers at lakes for a long time. Before the car made the Great American Roadtrip commonplace, the early tourism industry was greatly promoted by railways, as one of our recent acquisitions makes clear. The Burlington, Cedar Rapids & Northern Railway published a travel guide in 1901 for Spirit Lake and the Okobojis, a group of glacial lakes in northwestern Iowa that is sometimes referred to as “Iowa’s Great Lakes.”

Crandall’s Lodge, Spirit Lake, North Shore

This 31-page pamphlet gives plenty of information for the potential traveler who might be considering these Iowa lakes for their summer destination, including a description of Spirit Lake, information on where to stay, points of interest, and things to do. Here is its description of Crandall’s Lodge, “the most noted” resort on Spirit Lake: “There are none of the restraints of a fashionable summer restort at Crandall’s Lodge, but visitors here come to have a good time, unhampered by anything that will prevent the fullest enjoyment. …The beach facing the Lodge is the finest on Spirit Lake. It is quite wide, floored with clean white sands, dipping so gently into the water that bathers can go out a great distance before getting beyond their depth. This is the most popular pastime at this resort, and the merry shouts of children in play upon the sand or sporting in the water are heard from morn till night. …The rooms are large, well furnished and comfortable. The table is supplied with an abundance of well cooked and well served food. The cream, milk and butter come to the table fresh from a herd of thirty-six thoroughbread cows, and the supply is never in the least stinted. The vegetables are fresh from its own garden, which is the especial pride of Mr. Orlando Crandall, the founder of the Lodge. The rates here are most reasonable. Transients are charged $2.00 per day or $10.00 per week, with special rates to families.” The Lodge is a good 6 1/2 miles from the railway station, but the proprietor will meet visitors at the station for the scenic drive along the lake to the lodging. A family friendly swimming beach, large rooms, local foods, and reasonable rates…what more could even a modern tourist ask for?

The young “bathers” look a little different from today, don’t they?

Where did these visitors come from? The B.C.R. & N. railway “has a direct line from Chicago, Peoria and St. Louis to Spirit Lake. It maintains a double daily service between Chicago and St. Paul and Minneapolis….”

Map of the Spirit Lake/Okoboji area showing the railway and attractions.

Now, who’s ready to join me at the lake?

History of the Library, Pt. 3

This is the third in a series of posts about the history of the library at Iowa State.  Want to catch up? Read the first and second posts!

The library has been through many expansions through the 20th century to meet the demands of a growing student population. Iowa State had a new library in 1925, but as quickly as 1930 the collection was too large for the bookshelf space. In 1940, an off-site storage facility was built to handle some of the overflow that had been stored in the Memorial Union and the Engineering Exhibit Hall.

While the collection already exceeded the size of the library, there were other pressures put on the library space starting in the mid-century. The university experienced a great period of growth after WWII due to the GI Bill and the Cold War, when the government was eager to fund the scientific research done at Iowa State.  This period of growth was exacerbated by the incoming Baby Boom students.  All of these factors put great pressure on the amount of study space in the library.

To address these issues, the first expansion opened in 1961. The new addition had 5 floors and added 52,000 square feet. One big innovation for this addition was open stacks, allowing students to browse the shelves and pick out books themselves. A glass rotunda was built for the new entrance on the south side of the building complete with staffed circulation desk to make sure materials did not make their way out of the library without being checked out.

Even brand new, the expanded library could only accommodate 75% of the 520,000 volume collection and did not contain the amount of study space recommended for the size of the student population. Tellingly, even as they were building the addition, it was referred to as the “First Addition”, which brings us, inevitably, to the Second Addition.

This addition was started in 1967 and completed in 1969. This expansion more than doubled the space for storing books and for users to work.*

In the 1969/70 school year, the library offered 7 courses. There were 4 undergraduate courses, each designed for students in different areas of study: home economics, sciences and humanities, engineering, and agriculture. Additionally, there were 3 courses, each aimed at different groups of graduate students.
