Classification systems – we all know them (even if our readers don’t), we love them, we dislike them, we use them every day. Many Bodleian Libraries use Library of Congress (LCC), but it’s not uncommon, especially for College Libraries, to have their own classification systems (Jesus College being no exception). These in-house systems can be a pain – for example, we do not have a General Chemistry section and nobody knows why – but they offer a lot of flexibility to adjust to both your readers and your collection. Sometimes, of course, that means that shifting, updating or reclassifying of the books is required, whether for the sake of accuracy, facilitating easier browsing or improving outdated elements of the collection. As part of our ongoing effort to make the library more accessible, diverse and inclusive, I have recently undertaken several small reclassification projects and am in the process of working my way through more.
Before I get into the thick of it, here is an example of our classification system at work: if I were to write a book about music culture in East Germany, it would be shelved under LG7 LAM. The last three letters denote my surname (Lammers), the first three digits the location. L is Jesus’ letter for History, LG for German History, and LG7 for German history 1945-89. While some sections have fewer initial digits, the underlying concept remains the same.
Project 1: Linguistics

This was the biggest and first classification project I undertook. Until a few weeks ago, all of our general linguistics and translation books lived in NE2. As you may be able to deduce, N is our Language section, with NE being English Language. Not only is the housing of general linguistics books in this particular section confusing, it also posits English as the default language. Given the history of the British Empire and the prevalence of English to the point of eradicating and replacing others’ languages, this arrangement is highly problematic in its implications.
To remedy this, I browsed NE2 and pulled out all books that were not primarily about the linguistics of the English language, collected them on my desk until I was thoroughly walled in before changing their shelfmarks in ALMA, the software behind SOLO. I also changed the shelfmarks on the books’ title pages and went through an entire roll of label protectors and many sheets of stickers for relabelling before shuffling around NE1 and reshelving them. The new section is now N2, Linguistics, and NE2 remains English Language and Linguistics only.
Project 2: African History
The second project was much smaller in scope. Our African history section, comprised of around 60 books, had all been living in just one shelfmark: LV1. This was strange since, usually, when sections are not subdivided, they do not contain numbers. In itself that doesn’t necessarily create a problem, but it did lead to several situations where books were mistakenly classified as LV instead of LV1. The idea of tidying that up and creating subsections had been floated a while back, and I finally decided to go ahead with it.
In addition to our LV1 confusion, there were two other reasons for overhauling the African history section; firstly, there were enough books on a variety of topics (from Nelson Mandela to medieval Egypt and nineteenth-century colonialism) that having separate sections would make browsing easier and thereby improve accessibility and usability for our students. Secondly, expanding the level of detail for underdeveloped subsections is an important part of reducing the impact of past colonialism on our libraries.
Subdividing the section means that our classification system acknowledges the breadth and depth of African history, even if is smaller than, for example, our British History collection. The relative sizes of our collection of course correspond to the subjects taught at Oxford, but by affording the same care and attention to both, we are ensuring that we do not maintain an approach to African history that perpetuates colonial ways of thinking about African history. Colonial attitudes, by virtue of inherent inferiority/superiority dynamics, disregard and erase the diversity of African histories, cultures, lifestyles, beliefs, and more.
There is, however, an important caveat: if we had a mere ten books in the section, subdivisions may be superfluous. This is because they serve a primary purpose of discoverability, and this is already given if there is a small number of items to begin with. As such, our African history section may have once been too small to warrant the divisions but, as it continues to grow, it is vital to pay attention to when a pragmatic choice of action becomes a politically charged, problematic choice of inaction.
Unlike N2, where the new section already had a clear name and purpose when I started, for LV I needed to start with researching which subdividing system would work best for our collection and our students. While most of our history sections are divided by time period, a geographical division may have made more sense depending on the items we have. With an ALMA-generated list of everything classified under LV1, I got to sorting them into the two possible subdivision styles. I consulted Wikipedia for broad, sensible chronological divisions that would allow for some flexibility but adhere to the general pattern of historical developments on the African continent. I soon noticed that a system based on geographical region would end up looking extremely skewed, therefore rendering the potential for easier browsing moot, and so I settled on a time-period-based reclassification. The time periods I chose to use as subdivisions allow for growth and future changes within the collection. Our new African history classification now looks as follows:
LV1 – General
LV2 – to 1884
LV3 – 1884-1960
LV4 – 1960-
Currently we don’t have any books on African history prior to the medieval period (except for what is in Ancient History), but this system allows for an integration of these should we acquire them!
Project 3: History of Gender and Sexuality
This project was entirely the spontaneous work of an afternoon in week six of Hilary, which also happened to be during LGBTQ+ History Month. I was in the process of assigning a shelfmark to a new acquisition (The Shape of Sex: Nonbinary Gender from Genesis to the Renaissance by Leah DeVun), and, as tends to be the case, multiple options appeared as appropriate: LB, for European history, L1, for General history, or S7, for Family and Women’s Studies, which is where lots of our queer books live. I opted for L1, my manager for LB, and so I wondered out loud if we had enough books on historical aspects of gender and sexuality to just create an entire subsection. At that point we had L1 for General history and L2 for History of science, and lots of lettered subdivisions by geographical region. After receiving the go-ahead to do some investigating, I used my tried-and-true method of browsing the shelves and also did several subject searches on SOLO, limited to the holdings of Jesus College Library. I came up with about 30-40 books which were worth grouping together. I pulled books from General History and Family and Women’s Studies but left any period-specific books in their original subsections. As you can probably predict, I then went into ALMA records, crossed out old shelfmarks and stickered plenty. As for the name of the new section, I landed on “History of Gender and Sexuality” after consulting with both my manager and my fellow trainees. While I really loved the idea of its shelfmark being LQ, all the other lettered subsections in L (History) denote geographical regions rather than discipline related subtopics, so we agreed on L3 to reduce the potential for confusion.
The inclusion of history of gender and sexuality as a subcategory serves as a useful pointer for those interested in queer history and related subjects and highlights queerness explicitly rather than letting it disappear in the depths of General History. That is not to say that everything in general history is automatically less important, but a subject like History of Gender and Sexuality is so young that its own shelfmark can serve as a pointed nod that we value and appreciate this part of the collection.
Projects to come: Asian history and 21st century philosophy

Our Asian history section, containing approximately 275 books, could definitely improve in terms of browsability, consistency and the amount of outdated and/or problematic language used. I am currently working out what a good alternative would be that both serves our students needs and does our collections justice. I am also soon going to be taking a look at the contents of Q14, which is our later 20th century philosophy section and bursting at the seams. We don’t yet have a separate 21st century philosophy section, even though some of what is housed in Q14 may be better suited to living there. So, if you find yourself in Jesus College Library and Q15 does not yet exist, please feel free to hound me about it!
Something unusual about all of these classification projects is that I did them all in the middle of Hilary term. The regular order of procedure for any kind of reclassification project is to wait until the end of term, so that the amount of disturbance is kept to a minimum and that the maximum amount of books are back on the shelves. However, since many of the books could have been checked out and therefore not included in my reclassifying adventures, I take great care to pull out all potential candidates out of the returned books pile to subject them to the same procedures so that the end result can be a uniform, logical classification system.
While I know that many of our students never really become aware of our classification system as A Thing underlying the entire library, and deal with it only in the context of finding a specific book they already know the title of, these reclassification endeavours are important – not only for addressing and reducing the impact of colonialism, but also for inclusion efforts, for improved usability of the collection, and most importantly, for the case that a student does look at our system, and is not taken aback by an inherited, flawed classification system that is long overdue an update. Making people feel welcome and that they and their history belong in the library is crucial. While our material focuses on providing study material, it is also nonetheless meant to be a place where students feel welcome and seen.
