CLUSTER BOOK-BOOKS-CATALOG · 7 ENTRIES · EARLIEST ENTRY 2020-03-15

OPDS catalog desktop readers

These products are catalog browsers and readers for public-domain ebooks, pulling from OPDS catalogs (including Project Gutenberg) to let users search, browse shelves, and download titles. The cluster's dated history is too thin to read a shape from, as only three dated entries predate the index start. Traction leaders by activity signal are OPDS-Desk, opdsreader, and Bindery, though each shows zero stars.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 7 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
