What is inside the archive?
The Digital Library of India holds scanned books in many Indian languages, and its catalogue rarely says what a book is about.
The archive’s own subject field turned out to record where a book was scanned, not its topic. So the study reads the pages and groups books by what they say.
The archive as a map
Every book is a point. Books whose pages read alike sit close together, whatever script they are printed in.
What the study found
The targets were set before any result was seen. The results are on the study page.
A catalogue card for one page
Give the app a page and it drafts a catalogue entry from the archive books the page sits closest to.
Scan quality
Some scans are too faint or damaged to read well. The scan-quality page sorts every book into fine, read the scan again, or scan the book again, and says why.
Editions
The same text was often printed more than once. The editions page lists books that look like other editions of a book, with the title and author match behind each one.

Everything shown here is live on this site, and every figure comes from the study’s own result files.
