The EJLPP: Our Story

--Kathleen M. Comerford

The EJLPP began with the attempt to identify the full bibliographical information for inventory lists, found in Florentine and Roman archives, relating to the contents of libraries in Jesuit colleges of Florence (1565 and 1578) and Siena (1565).  The notaries who recorded that information intended them to be used by the Collegio di San Giovannino in Florence and the Collegio di Siena (later called the Collegio di San Vigilio), so they simply wrote basic identifying information, along the lines of "Io: Gersonis opusculum" and "Revelationes S. Brigida." I have undertaken to decipher these inventories and to create a companion census of books once owned by other Jesuit libraries, hoping that this particular window into the Republic of Letters can provide us with insight into what our early modern counterparts read, what they learned, and what they did with that learning.  Among the questions which interest me are: what was Jesuit about these books, or these libraries?  Were the members of the Society of Jesus really "the first globalists," as some have claimed?  What was it like to be a teacher in the Jesuit colleges?

The European Jesuit Libraries Provenance Project has to date proceeded along the following steps.  The collected information is "housed" in a series of spreadsheets.  

  1. seeking out relevant archival documents, including library inventories, to convert the basic identifying information into bibliographical references

  2. collecting biographical information on authors  

  3. seeking out physical copies of books found in those inventories, and books by authors found in the inventories, to collect provenance information

  4. seeking out digital copies of books found in those inventories, and books by authors found in the inventories, to collect provenance information (using word processing, spreadsheets, digital collections of libraries, and online repositories like Google Books, Hathitrust, and the Internet Archive).


I will periodically update the inventories; students are working on the Digital Commons site.

  1. Combined inventory of multiple European Jesuit institutions' pre-suppression libraries ones I have seen in person (Siena, Florence, Bologna, Livorno, Bagnacavallo, Antwerp, and Leuven)

  2. Inventories transcribed from printed sources (currently St Omer, Delft, Maastricht, Irish College).  I will add them to this file.

  3. Census created from modern library catalogues, including books I have seen as well as those I have not

  4. Digital Commons site, with photographs of books I examined at Yale and Emory Universities and at the Folger Shakespeare Library.  I own the copyright for these images.


We are still collecting data--and will continue to do so for the foreseeable future.  However, in the meantime, we are also engaged in interpretation.  The most significant interpretive project to date is the capstone project completed by Lauren Della Piazza Hartke in the pursuit of her MA in Public History (Georgia Southern University, May 2020).  Lauren has graciously consented to share her thoughts in a recent blog post (April 14, 2020), and has provided an excerpt from her written project for me to post here.  Please look at her graphs and interpretation of the data on books associated with English Colleges prior to the suppression.  Data visualizations can teach us a great deal about books and readers!
