Automated Clustering of Running Titles to Uncover the Printing Process of Early Modern Books

Core Concepts

A novel computational approach to automatically cluster the running titles in early modern printed books in order to detect variations in the underlying skeleton formes used during the printing process.

Abstract

The authors propose a computational approach to automatically cluster the running titles found at the top of pages in early modern printed books. The goal is to detect variations in the underlying skeleton formes used during the printing process, as the running titles were often reused across pages printed with the same forme.

The authors design two custom kernel functions to compute the visual similarity between running titles - a Levenshtein-based kernel that captures differences in character spacing and shape, and a neural cross-encoder Vision Transformer-based kernel trained on synthetic data. They then use spectral clustering on the similarity matrices to group running titles printed with the same skeleton forme.

The authors evaluate their approach on a newly introduced dataset of 8 early modern books across different formats, with ground truth annotations of the skeleton forme clusters provided by expert bibliographers. They find that their domain-informed Levenshtein kernel significantly outperforms the neural approach, and that leveraging the book's gathering structure to aggregate similarities across sheet sides greatly improves performance compared to using individual pages or recto pages alone.

The authors also provide a detailed qualitative analysis of their results on the Leviathan book, showing how their automated clustering can uncover important bibliographic insights about the printing process, such as the use of multiple presses, pauses in printing, and cancellations.

Stats

The format of the book was determined by the number of pages printed on each sheet of paper.
Leviathan was printed in folio format, with 2 pages per sheet side.
Paradise Lost, King Lear, Mayor, and Parthenissa were printed in quarto format, with 4 pages per sheet side.
Institution, Discourse, and Wisdom were printed in octavo format, with 8 pages per sheet side.

Quotes

"Increasingly, AI methods are being applied to historical texts in order to enrich our knowledge about past cultures and societies, ranging from ancient Greek inscriptions [2] to Akkadian tablets [11] to Latin [3], early modern English and Islamicate books and manuscripts [23], inter alia [21]."
"The forme—not the page—was the basic component of early modern presswork; and the page order of early printed books was established by folding sheets."

Deeper Inquiries

How could the proposed approach be extended to handle books with more frequently reset running titles, such as the King James Bible?

The proposed approach could be extended to handle books with more frequently reset running titles, like the King James Bible, by incorporating additional features or techniques to capture the unique printing patterns of such books. One way to address this challenge is to develop a more sophisticated feature extraction method that can differentiate between subtle variations in running titles that occur due to frequent resets. This could involve leveraging advanced image processing algorithms to detect and analyze these variations more effectively.
Furthermore, the model could be trained on a more diverse dataset that includes a wider range of books with varying printing practices. By exposing the model to a larger corpus of early modern printed books, including those with frequently reset running titles, it can learn to adapt to different printing styles and patterns. This broader training data would help the model generalize better and improve its ability to cluster running titles accurately in books with more complex printing histories.
Additionally, incorporating domain knowledge from experts in early modern printing practices could enhance the model's performance. By integrating insights from bibliographers and historians who specialize in the production of early modern books, the model can be fine-tuned to recognize specific characteristics and anomalies associated with books like the King James Bible. This domain expertise can guide the development of more nuanced features and similarity metrics tailored to books with unique printing processes.
