Mapping pre-1500 Printed Books Today


Last week the Penn Libraries hosted a Rare Books School course on the 15th century European book in print and manuscript taught by Will Noel and Paul Needham. As someone interested in the history of libraries and the movement of books over time, I've long been impressed by the volume of detailed information available in digital form about early European printed books. Online catalogs like the Incunabula Short Title Catalog (ISTC) and the Gesamtkatalog der Wiegendrucke (GW) contain tens of thousands of entries about these books including the whereabouts of known copies today. In browsing both catalogs I had been surprised by the wide distribution of incunabula in libraries throughout the world and inspired by the work of the Atlas of Early Printing, I figured it would be interesting to see the global scope of these collections in visual rather than textual form.

Both the ISTC and GW allow users to browse by lists of libraries which hold incunabula but where the ISTC displays library abbreviations/codes (see e.g. this list), the GW actually lists geographic locations with libraries grouped by city. In addition, the GW provides helpfully detailed alternate spellings and names for locations which make them easier to geocode, for example:   "Alba Julia [Gyulafehérvár, Karlsburg, Weißenburg]/Rumänien." For that reason I decided to use data from the GW here, which in all contains listings for some 2,330 place names with institutions holding incunabula. 

I scraped the raw data from the GW web interface and then parsed it on my own which resulted in a few problems, namely while I captured all the place names accurately, some holdings libraries seem to have been lost in the shuffle. I've worked to manually correct these but would not be surprised if further corrections are needed. Likewise, the GW helpfully lists some libraries which formerly owned incunabula and which are now defunct or subsumed into other libraries.For example, for Philadelphia, I know that the number of holdings libraries listed (19) includes the former Mercantile Library of Philadelphia with 5 incunabula. All of these books are now in the Free Library of Philadelphia which means that the total for Philadelphia in my visualization includes one extra holdings location and 5 extra incunabula. In addition, and most importantly, my results from the GW are most useful in counting editions rather than actual physical books. That is, while there may be just over 5,000 separate 15th c. editions in Stuttgart, the Landesbibliothek there holds closer to 7,000 actual 15th c. books as a result of having multiple copies of the same edition (many thanks to Paul Needham for pointing this out). As a result, the exact numbers contained in the visualization should be taken with a grain of salt.

Top 15 cities by holdings of Incunable editions. Number of editions in center column, number of holdings institutions in a given city in right column.

So, despite these caveats, what does the data look like? The top 15 list is hardly surprising, Munich tops the list thanks to the Bayerische Staatsbibliothek and its massive collection, but thinking geographically rather than nationally, Rome would come out as the clear winner if Vatican City and its libraries were included. Likewise, if judging by number of libraries/institutions reporting incunabula holdings (admittedly a somewhat hazy category), London emerges as the extreme outlier. I found the numbers further down the list more surprising, I would not have guessed that Dallas (1013) holds roughly the same number of early printed editions as Zurich (1002) or that Copenhagen (4146) would have a more diverse collection than Venice (3464), one of the centers of early printing.



That being said, if anything the map hews more closely to the geographic origins of the books themselves than I fully realized (excepting the large holdings in the US of course!). The densest clusters of holdings institutions and indeed of incunabula themselves are in the homelands of early printing, German-speaking central Europe and Italy. Compare for example the two maps below, one from the current holdings data and the other from the excellent Atlas of Early Printing showing where incunabula were actually printed. The two pair up pretty well!

Current Incunabula Holdings in Europe (GW data)
Volume of Book Production by Place of Printing 1450-1500 (Atlas of Early Printing)
I expected that thanks to monastic dissolution and library centralization throughout the 19th century would have resulted in a fairly spread-out pattern of incunabula holdings with capital cities and regional centers being the big players with a few scattered libraries in between. This seems certainly to be the case in France and Spain where provincial cities and towns are less well-represented, but in central Europe, the big state and university libraries may have a large share of books, but there are still hundreds of small religious colleges, town libraries, and monasteries holding incunabula in the hinterlands. (If anyone is interested, the weighted geographic center of all current institutions holding incunabula is near the Atlantic coast of France outside of Nantes).

Incunabula holdings in the Adriatic Region
These maps also drew my eye to blank spaces which in turn highlighted borderlands between book-dense areas and those with relative scarcity today. The Adriatic seems to be one such area, with its string of Catholic and state libraries extending down the Croatian coast including Dubrovnik, Zadar, and Šibenik serves to highlight the lack of 15th-century printed books in the interior of the former Yugoslavia - perhaps reflecting the ravages of war, different book/manuscript cultures in Orthodox and Muslim regions, or just the simple lack of good library data.



Something similar struck me about the region to the east of Berlin and the west of Poznan, a seemingly "empty" salient stretching south from the Baltic sea (left). I know next to nothing about this area but would have thought expected a more even distribution of libraries.


Of course, scale is everything. While the views above are intended to highlight cities which possess truly significant incunabula collections, the map below is perhaps a fairer representation of the data - with the sizes of the dots scaled by quartiles. In this view, the truly broad range of holdings locations comes into play, as on this map the top quartile (largest dot) is reserved for any place holding 65 incunabula or more - a seemingly low bar which reflects just how many locations own a very small number of early European printed books.
Current Incunabula Holdings Worldwide - scaled in quartiles.

Finally, this world-view impressed on me the lack of reported holdings in North Africa and the Middle East generally. The fact that there are only four incunabula from Istanbul reported in the GW is somewhat shocking (for more see Les incunables de la bibliotheque des Musees Archeologiques d'Istanbul). Considering the place of the Ottoman Empire in Mediterranean and world history, the lack of greater numbers of early printed books in Turkish libraries begs an explanation (library destruction? lack of cataloging?). Likewise, the lack of reported holdings in Egypt prompted me to start searching library catalogs. I found six unreported in the new Bibliotheca Alexandrina but am sure there must be more in other Egyptian libraries as well.

I look forward to discovering more in the data over the coming weeks and I can't stress enough how important rich bibliographic databases like the ISTC and GW are for scholars. They are exceptional resources that took decades of work to put together. Given the amount of work that went into creating their data I hope that in the future there will be a way for both to offer machine interfaces which make the downloading of raw data simple and these kinds of visualizations second nature to researchers.

Expanding the Republic of Letters: India and the Circulation of Ideas in the Late Eighteenth Century

Today I'm presenting at the Society for the History of Authorship, Reading & Publishing (SHARP) annual conference which is being held here at Penn. Rather than giving a traditional conference paper I will be participating in the "digital project showcase" which features a number of really fantastic digital book history projects. I thought it would be helpful to post here some of what I will be showing today at the conference.

My project was inspired in a way by one of the most successful visualization projects of the last few years, Stanford’s Mapping the Republic of Letters project (ROL). The project uses data about thousands of seventeenth and eighteenth century letters to provide a powerful visual representation of how intellectual and correspondence networks functioned over the long eighteenth century. The visualizations that result from the project are quite powerful and illustrative and have immediate impact on students and others trying to get a sense of the geography of the Enlightenment. Taking as an example the 1751-1800 period below, one finds in the ROL visualization what one might expect: Paris, London, Edinburgh, Geneva, all show up
brightly as nodes of discourse and communication:



Without diminishing the ROL's achievements though, I was immediately struck by the absences encoded into this sweeping view of the Enlightenment. As a historian of 18th-century India, I was especially concerned about what it meant that it is visualized in the ROL as connected to the European Enlightenment in this period by just a single slender line: 

In my own research on legal culture in early modern India I had long been struck by the ways in which legal information and texts flowed in all different directions between and through India and Europe. For the SHARP showcase then I proposed a new visualization of the eighteenth-century, one which would focus on circuits of knowledge exchange in the form of textual movement between India and the rest of the world.

The resulting project is based on extensive research and data from wills, inventories, auction and library catalogs, as well as correspondence and other records. To be more precise, the visualizations below come from some 2,400 mentions of print and manuscript texts sent to India from abroad or which were produced or owned in parts of European-ruled India. Spelling out these sources I think makes clear the limits as well as the potential of the project. Records of book ownership and text circulation in 18th-century India are difficult to get at and since my goal was to show connections with the wider world, I necessarily focused on nodes of greatest contact, especially the East India Company port cities of Bombay, Madras, and Calcutta, as well as other European enclaves like Tranquebar and liminal zones like Lucknow. Much is obviously lost in this survey, especially the enormous body of Persianate literature that circulated throughout central and south Asia as well as those texts which moved between China, southeast Asia, and India. Yet for now, there is only so far I can go and I look forward to building on the project with the assistance of other scholars.

So what were the results:



Instead of that measly thin line connecting India with Europe in the 18th century we see a robust array of connections. The blue lines represent texts flowing from Europe/Americas to India and, perhaps more importantly, the red lines represent texts moving outward and within India. Though you can manipulate the visualization above as you chose I thought I would highlight some of the more significant questions that I think come out of this view. 

First is the need to look beyond print to see networks of circulation. In his impressive bibliography of printing in South Asia, Graham Shaw lists just 1,344 imprints from mainland South Asia before 1800 (Another 427 come from Dutch Sri Lanka). Many of these books were printed in extremely small numbers and are not known to have circulated particularly far. As a result, the print connections between Indian-produced materials pale in comparison to the inflow from Europe. If we select only flows of manuscript material however we remove much of those large blue print-lines from Europe and see a richer picture of the circulation of Indian texts:

Movement of manuscripts to and from India c. 1750-1800

In addition to showing the movement of texts in aggregate I also wanted to be able to say something about the nature of these texts. Thinking of the Stanford ROL project I decided to see what the movement of texts by authors whose correspondence is represented in that project (~40 or so including Adam Smith, Voltaire, Rousseau, and Locke). Their texts were some of the most popular in my records though notably, because of the nature of the data, most in English translation:

Flow of texts by "Enlightenment" authors c.1750-1800
This kind of geographic visualization also flattens different kinds of textual transmission. Should the fact that an English soldier in Calcutta owned a European-printed copy of Goethe's Sorrows of Young Werther be represented equally with the fact that a pirated translation was printed at Calcutta in 1792 (though no copy survives today)?

Though slightly disappointed with the informational value of the Enlightenment authors map, I was more curious about those texts which I labeled as being broadly scientific, algebra texts, accounts of experiments, journals of temperatures, Persian treatises on medicine, etc. :

The map to the right shows the interplay and diversity of transmission of these "scientific" texts. Rather than a homogeneous block of European science entering India, there was a robust interested in locally produced scientific and medical accounts by authors of all kinds.

Yet, perhaps the most well distributed exchange of ideas seems to have taken place in the realm of historical texts and the accounts of political structures produces in both Europe and India. Though scholarship on early Orientalism has often focused on religious and philological translation and collecting, perhaps more than anything else, 18th century Indian readers and collectors relished histories. These included texts from Europe like Paul de Rapin's History of England or those from India like the Alamgir-Nama of Mirza Muhammed Kazim both of which circulated widely:

"Historical" texts and their circulation c. 1750-1800

I'm just starting to take a look at these maps in an attempt to formulate further research questions and I do hope readers will play with the interactive features to ask questions of their own.

Geographic maps only go so far though in representing this circulation of texts. They tend to aggregate and obscure individual books and historical actors. For that reason I turned to another type of visualization in an attempt to understand which books and readers featured most prominently in my data.







To the right is the bewildering array of connections formed when one plots texts with common owners, that is, who is connected by shared ownership of particular titles and what can that tell us about the circulation of texts in India. This view is of course barely useful in its current state other than to show a central cluster of connected people and texts and at the bottom an array of people and texts who remain unconnected. To see the full network in PDF form see here.

A different view of the same data I think proves more instructive:
Books (black) by size according to number of connections in the data
red dots represent individual owners




This view shows the very center of that cluster above, this time however, the size of each node (dot) is determined by the number of connections it shares with its neighbors. In this case the black dots represent particular titles and the red dots particular owners. The large nodes here are the most popular texts, including the Bible, the Works of Jonathan Swift, Alexander Pope, and Shakespeare, Addison and Steele's Spectator, a variety of print and manuscript Persian dictionaries, Tristram Shandy, and the classic Persian prose work, Sa'di's Gulistan. Looking further afield from the classics though there are some interesting questions to be asked. I noticed in perusing the records that two Bengali men in Calcutta seemed to be purchasing a number of books at estate sales. One of these, "Gopee Tagoror [Tagore]" seems to have been especially interested in anti-onanism tracts. In fact in 1767 he bought a hot-of-the-press warning on the "Detestable Vice of Self-Pollution" [ESTC T207134] which is today only held in two libraries worldwide. Was he a bookseller? A fan of self-improvement literature? A committed anti-onanist?There is much to interpret here and I hope both at today's showcase and in future conversations to begin mining these connections for what they can and cannot tell us about the cultural world of colonial India in the late 18th century.
Gopee Tagore's books 1767

As a final coda, just hours away from the showcase itself, I'm completely humbled by how frustrating a task this proved to be. At the end of this stage of work I realize just how central absence and omission are to any visualization of historical information. No matter how much I tried to "fill in the gaps" my visualization remains constrained by data available and historical uncertainty and I've come away knowing that while I may have added a useful addenda to the vision of the Enlightenment that ROL offers, it is far from complete and perhaps offers its greatest value in forcing us to ask what is missing.
