The project’s major work and accomplishments were (in relation to the above-stated objectives):
1. Corpus, technological base, and web platform. We released eight versions of the corpus (latest version:

https://doi.org/10.5281/zenodo.11501559(odnośnik otworzy się w nowym oknie)). The corpus and reuse data are now featured in the Digital Library of the Middle East:

We detected more than 1.6 million overlaps between pairs of books and mapped the relationship of every book to all others in the corpus. Our open access web platform (kitab-project.org/explore) allows other researchers, including those without technical backgrounds, to explore our texts, data, visualisations, and findings. We also partnered with other projects such as the Arabic-Script Optical Character Recognition Catalyst Project (AOCP) to improve automated text recognition for both print and handwritten texts; developed computational methods to track and analyse citations; and created a Python library in wide use by other projects. We relied more on machine learning than we had planned, which prepared us for the major developments, towards the end of the project, in AI.
2. History of the book in Arabic. The project team produced four monographs; two PhD dissertations; and thirteen journal articles and book chapters treating the following themes:
Authorial practices: Topics included premodern understandings of authorship, the cultural meanings associated with different forms of transmission, and ideas about originality. We used quantitative analysis, assessing, for example, the proportional representation of highly prolific authors in the overall textual tradition: we were surprised that these authors reused earlier works at approximately the same rates as less prolific authors.
Changing forms of the book: We problematized the very idea of the Arabic book as a fixed entity, exploring instead the ways in which textual fragments in books took on lives of their own within anthologies, encyclopaedias, multi-text compilations (majmūʿāt), commentaries, and abridgements (mukhtaṣars) and extensions of books. We distinguished writerly practices across the period as distinct from later print culture, as we emphasized the persons and networks that produced and reproduced texts.
Narrative adaptations. We looked closely at how frequently copied texts and parts of texts were adapted over time, with the objective of discerning the formation of narratives, often in conflict with one another, out of heterogeneous past material. We considered specific communities and such changes to narrative to discern interests at work in the development of textual meanings.
3. Identification and exploration of the workings of cultural memory. We connected our work on book history to cultural memory, as we focused on how memories were communicated, circulated, and exchanged in the medieval Islamic world; how the recombination of previous texts in new book forms revealed the ways in which groups defined themselves; and how groups, through texts, negotiated their shared pasts. These topics were treated in our publications above, but also in the very architecture of the project itself, as we built the data sets and visualisations to document changes across time (the best example being our ‘one-to-many’ data visualisation, which enables investigation of the prevalence of a theme across time).
Regarding the monographs, two companion volumes will be released in 2026 through Edinburgh University Press: The Making of the Arabic Book: How Text Reuse Built a World Tradition (Sarah Bowen Savant, with Masoumeh Seydi as data co-creator) and Digital Explorations of Memory and Community Formation Through Text Reuse (Mathew Barber, Lorenz Nigst, Aslisho Qurboniev, Gowaart Van Den Bossche and Peter Verkinderen). A further two volumes treating book history were produced by Van Den Bossche (De Gruyter, 2023), Literary Spectacles of Sultanship: Historiography, the Chancery, and Social Practice in Late Medieval Egypt, and Maxim Romanov, Digital Humanities for Arabic and Islamic Studies: A Proposition for the Field (De Gruyter Brill, 2026).
