CLUSTER READER-BOOKS-BOOK · 40 ENTRIES · EARLIEST ENTRY 2013-03-25
Cross-platform e-book readers
This cluster comprises desktop and cross-platform e-book reader applications focused on reading EPUB and other digital book formats, with some positioning for accessibility. Dated entries before the index begin sporadically in 2010 and 2013-2017, then appear more consistently from 2022 onward, with the largest pre-index monthly counts in 2026. TextbookLens leads on traction with 31 stars, far ahead of openthebook (2) and moon-reader-replica (0).
Entry timeline
ENTRY TIMELINE
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.
