Charlton Hinman, Optical Collation, and the Big Grey Machine

January 12th, 2026

Charlton Hinman was a looker. Of course, that was true of so many of Fredson Bowers’ students – they tended to be lookers. We won’t make any comment on the relative attractiveness of Charlton Joseph Kadio Hinman or Bowers’ students, but we refer instead to the tradition of close examination and description of books that Bowers codified and Hinman continued here at the University of Kansas. On the north side of the Marilyn Stokstad Reading Room at Kenneth Spencer Research Library is the Hinman Collator, a hulking grey machine that stands as a reminder of (and a tool for) precisely that kind of work. Our colleague Caitlin Klepper wrote a post about the collator previously, but we thought we might delve more in-depth here.

Modern descriptive bibliography – the close physical examination and description of books – begins with Fredson Bowers’ book Principles of Bibliographical Description (1949). Bowers was a professor of English at the University of Virginia, and Charlton Hinman was Bowers’ first PhD student there. Both Hinman and Bowers had analytical minds with similar bents, which served them well in the Second World War. They were involved in cryptography and code breaking, with Bowers again leading Hinman as his commanding officer. Following their service, Bowers returned to Virginia, publishing the aforementioned Principles.

Hinman’s dissertation, The Printing of the First Quarto of Othello, led to his first position as a research fellow at the Folger Shakespeare Library, where he collated copies of the first folio of Othello. It was Hinman’s time as a fellow at the Folger that inspired his creation of the collation machine. Collation – or, the work of examining and describing the physical evidence in a copy of a book – is time consuming. Hinman’s work was even more intensive, as he sought to find all of the different states of the pages down to the most minor corrections or insertions made by the printer in the course of printing the book. Looking at each page of text line by line is an almost impossible task. Hinman hints at this problem in his preliminary essay about the machine, which was titled “Mechanized Collation: A Preliminary Report” and printed in the Papers of the Bibliographical Society of America in 1947.

Hinman’s time in the military helped point the way to a solution, supposedly through military reconnaissance use of photography. He described the idea of taking two pictures of the same area and rapidly alternating them to spot differences. He didn’t claim he had done it as part of his cryptography work; rather, he claimed he heard about it while in the military. However, the process Hinman described was never used for reconnaissance purposes. While the military did use aerial photography, they didn’t use any method that alternated two images in a similar way to the function of the Collator. In his article “‘The Eternal Verities Verified’: Charlton Hinman and the Roots of Mechanical Collation” (Studies in Bibliography, 2000), Steven Escar Smith writes that “using World War II technology, it simply would not have been possible to photograph the same patch of ground twice from exactly the same altitude and position.” According to Smith, Hinman seems to have acknowledged that the story wasn’t entirely true, but it’s not clear whether he actually discouraged its telling.

Arthur M. Johnson, Hinman’s partner who took over building and selling collators around 1956, may have been the one to accurately describe how Hinman got the idea for the collator. Johnson wrote that Hinman had studied something that Johnson called an “astronomer’s microscope.” It used the same principle of “blink comparison” to compare images of the night sky, most famously by Kansan (and KU alumnus) Clyde W. Tombaugh in his observation of Pluto. Although it’s not known whether Hinman ever saw or used a blink comparator, he knew of the one at the observatory at UVA when he was a PhD student there. This was the true technological ancestor of Hinman’s machine.

These kinds of devices are simpler than the Hinman Collator in that one can use flat images of similar size – not possible with books. Hinman’s great improvement and contribution, then, was the creation of a machine that could deal with books of different sizes, thicknesses, and even formats. Hinman had a long career as a professor of English, first at Johns Hopkins University (1945-1960) and then at the University of Kansas (1960-1975), where he eventually became a University Distinguished Professor of English. Approximately 50 collators survive. The collator at Spencer (A9 in Steven Escar Smith’s 2002 census of existing Hinman Collators, published in Studies in Bibliography) is one of two that remain that Hinman himself used; the other is at the Folger Library. The effect of the collator is reproduced in this short video by Sam Lemley. Bibliographer J.P. Ascher has also made a good video about how one might use the collator, utilizing the machine at the University of Virginia.

Hoping to actually use Spencer’s machine, we ventured to the Reading Room before opening. We powered it on, and, to our delight, the 400-pound machine came to life. Unfortunately, this was not to be, as we discovered that the “blink” feature, the key function, is not currently working. Thanks to the efforts of our colleague Molly Bauer, we are slowly learning what might be wrong and what the fix might be. Look for a follow-up post in the spring about our efforts, as well as digital alternatives to optical collation that bibliographers can use today.

The Hinman Collator, for now, stands as a testament to the ongoing work of descriptive an analytical bibliography here at the University of Kansas. Much like its creator, the machine is complicated and devoted to a very specific purpose – close looking at material objects we regularly take for granted.

Student Spotlight: Oliver Grotegut

April 8th, 2025

This is the latest installment in a series of posts introducing readers to student employees who make important contributions to the work of Spencer Research Library. Today’s profile features Oliver Grotegut, a Cataloging and Archival Processing student assistant and a G. Baley Price Fellow.

Please provide some brief biographical information about yourself.

I am a senior at KU majoring in linguistics with a minor in sociology. I started working at Spencer in March 2024.

What does your job at Spencer entail?

My job is to inventory University Archives materials so that ArchivesSpace, our online collection database, can be updated. We gained quite a lot of material in the years since the last update, so this long-term inventory project ensures that anyone can easily find materials we have available in the University Archives.

Why did you want to work at Spencer Research Library?

I wanted to work at Spencer, or really in archives in general, because I was interested in a job optimizing materials for public use and finding relevant patterns and throughlines in large groups of information. I knew that library or archival work was the ideal field to find such a job. I feel my time at Spencer has provided me with an invaluable amount of knowledge from hands-on learning about archival work, information organization, and document care and preservation that I look forward to bringing with me into a career in archives.

What has been most interesting to you about your work?

There has been a lot I have found enjoyable about my work. It has been especially interesting to sort through decades worth of accepted and denied grant applications and project proposals, and seeing what research was considered novel and worthwhile over the years. By far my favorite record group to inventory so far has been the student housing records. So many of the materials in that group – scrapbooks, incident reports, event planning forms – exemplify what life was like for KU students at any given time.

One I think of the most often is a document from the 1950s where all the residents of Miller Hall explain why they would or would not be alright with having a African American resident move into their scholarship hall the following year. The residents provided in-depth, incredibly honest descriptions about their perspectives on the matter. Rightfully, much of the education and discussion of the civil rights movement focuses on the actions and experiences of African Americans at the time. Seeing the privately held opinions of white Americans at the time, especially those occupying all-white spaces, provides a great deal of further context to the realities of the climate at that moment in history. I also find it interesting sociologically that the matter of potentially having an African American resident in Miller Hall was considered worthy of being discussed and voted on, and the existence of the document says a great deal not just about the opinions of the residents but of the student housing administrators. For those interested, the majority of the opinions were in favor of racial integration, and Miller Hall gained at least one African American resident the following year.

On a lighter note, I also like getting to put new labels on the boxes.

“Snap Shots of My University Life”: The Student Scrapbook of Nola Ayers 

March 7th, 2025

Nola Mary Ayers was born in Horton, Kansas, in 1886. She arrived in Lawrence in the fall of 1905 to enter the University of Kansas and graduated from KU with a bachelor’s degree in 1909. Nola documented her college years by creating a scrapbook, as did many other university students at the time. 

Typically, students purchased a large scrapbook from one of the bookstores near the university. Nola broke with tradition by using a blank “Specimens” science notebook to paste in mementos of her life at KU.

Nola’s scrapbook was also unique because she was an artist and decorated her album with original pen and ink drawings. One of the first drawings in the scrapbook is a self-portrait where she describes herself as a “poor home sick freshman” whose “college home for the year 1905-06 was 1305 Vermont St. Lawrence, Kansas with Mother Dow to call us eight girls down.” This house on Vermont is still standing in the Oread neighborhood. In the years before dormitories, many students lived in boarding houses near campus; many of these large multi-story houses still exist. 

This image has text accompanied by a black-and-white sketch of a woman sitting at a desk. There is also a photograph of Spooner Library.

Nola documented her studies in her scrapbook. As seen in the image below, she took “Hygiene” and “Gymnasium” during her freshman year – courses that all KU students in the early twentieth century were required to enroll in. Nola also studied rhetoric, German, geology, solid geometry, and botany. Her scrapbook reflects her love of drawing, and her coursework included drawing, ornament design, and Greek art.

Besides coursework, friendships with other students are well represented in the pages of Nola’s scrapbook. She documented slumber parties with other girls, popcorn making, a Halloween party where she dressed as the “Western Girl,” and events at her sorority, Kappa Kappa Gamma. Nola celebrated Valentine’s Day with a party and red hearts pasted into her scrapbook.

As evidenced by her scrapbook, Nola partook many of the outdoor activities KU students enjoyed in the early twentieth century: walking, boating on the Kaw River, picnicking in the countryside, and attending sporting events. According to the 1908 Jayhawker yearbook, Nola was an “authority on baseball” and an “enthusiastic fan.” Indeed, she pasted photos of the KU baseball team into her scrapbook. Nola also included items related to the KU debate team. Debate was almost as popular as athletic sports during the early twentieth century, and students would travel to other cities like Topeka to support the KU team.

According to a newspaper article, Nola was crowned Queen of the May at the second annual May Fete in 1909. She was a member of Allemania (German Club) and attended their events. She appeared to have attended many dances, plays, and concerts while a student, as documented by the many programs decorating her scrapbook. Plays and concerts were held on campus and in downtown Lawrence at the Bowersock Opera House.

Nola Ayers married KU alumus Benjamin P. Young in 1910. According to a newspaper article announcing their wedding, the couple settled in Halstead, Kansas, where Ben was a high school principal. Ben and Nola relocated to Ithaca, New York, by 1923 and appear to have lived there for the rest of their lives. They had two children. Ben died in 1958; Nola passed away in 1973 at age 86.

Today in the Lab: Ask a Conservator Day 2024

November 1st, 2024

Today, Friday, November 1, 2024, is the fifth annual Ask a Conservator Day, an initiative of the American Institute for Conservation (AIC), the national professional organization for conservators.

Ask a Conservator Day serves a dual purpose. First, it commemorates the flooding of Florence on November 4, 1966, which damaged cultural heritage sites throughout that city and, in the aftermath of the disaster, sparked a massive recovery effort that is seen as the origin of the modern conservation profession. Ask a Conservator Day also serves as an opportunity for conservators and other preservation professionals to educate the public about the conservation profession.

In that spirit, I will revive our occasional Today in the Lab series to share a snapshot of what I am working on right now. The materials at my workbench always represent an ever-changing mixture of long-term projects and one-off treatments with a shorter turnaround time, and at any given time I will have items from all of Spencer’s collecting areas in my queue. So come along on a tour of my workspace!

First, on the green book truck next to my bench I have a group of recently catalogued children’s books from Special Collections, mostly from the 19th century. As my colleagues in cataloging complete their work on the records for these materials, they flag volumes that need repair or housing. Our team of Conservation Services student assistants have already made custom enclosures to protect these vulnerable books, and I have been working through the flagged items in batches to complete any needed repairs.

Next, I have several sets of architectural drawings for Watson Library, which is having its centennial this year. These sets are for the original 1922-1924 construction and a 1940’s addition, a total of 116 individual drawings. These drawings bear signs of being used on the construction site: edge tears and creases from frequent rolling and unrolling, builders’ markings in pencil and other media, and a significant accumulation of surface dirt. One by one I have been surface cleaning the drawings on both sides, flattening the creases, and mending the tears with a specially made repair tissue. Just 6 more drawings to go before these sets will be returned to the University Archives, where they will be available once again to researchers.

Moving on to my cabinet! Right now the upper section of my cabinet mostly holds materials that I have prepared for an upcoming temporary exhibit. I have made cradles or selected other supports from our supply of exhibit materials, and for now these items are simply waiting for the installation date. On the lower shelf, second from the right, is a very long-term treatment that is in progress, an early 20th century funeral ledger from the Kansas Collection. I have removed duct tape from the spine of the volume and have mended about half of the text block. When mending is completed, I will reinforce the sewing and board attachments so that this fascinating volume will be stable enough for use in the reading room.

Finally, in two of my lower cabinet drawers I have items awaiting treatment that have come to me either from cataloging and processing, or from the reading room. These are typical of the single-item treatments that make up the bulk of my daily work: items needing custom enclosures, volumes with detached spines or boards, rolled material that needs to be flattened, photographs that need to be removed from frames. This steady stream of “patients” is what keeps my day-to-day work from becoming boring or repetitive, as the depth and variety of Spencer Library’s collections means that I always have something new-to-me to work on.

That’s Distinctive!: KU Libraries Photos

September 20th, 2024

Check the blog each Friday for a new “That’s Distinctive!” post. I created this series to provide a lighthearted glimpse into the diverse and unique items at Spencer. “That’s Distinctive!” is meant to show that the library has something for everyone regardless of interest. If you have suggested topics for a future item feature or questions about the collections, you can leave a comment at the bottom of this page. All collections, including those highlighted on the blog, are available for members of the public to explore in the Reading Room during regular hours.

This week on That’s Distinctive! I am sharing some photographs from University Archives. Housing all things KU related, University Archives collects and preserves manuscripts, maps, blueprints, artifacts, photos, and more. The collection houses over a million photographs alone. As with last week’s post, this week’s images come from the library’s digital collections, which can be found on the “Find Collections” page of Spencer’s website. While not nearly all of the photos from University Archives are digitized, there are a ton to browse in the online collection.

The images shared this week show various scenes from inside KU Libraries. KU Libraries consist of six locations across campus: Watson (which is turning 100 years old), Anschutz, Spencer, Spahr Engineering, Art & Architecture, and Music & Dance. With over 5.6 million items on campus and even more available online, the libraries offer a wide variety of materials that serve users – especially KU students, faculty, and staff – and help them reach their goals. The Libraries’ mission is to “advance research, teaching, and learning at the intersection of people and ideas.” So while I boast that Spencer has something for everyone, every library on campus has something to offer.
