CLUSTER BOOK-EPUB-READER · 16 ENTRIES · EARLIEST ENTRY 2009-07-31

E-book readers with format support

This cluster consists of e-book reader apps supporting formats like EPUB, CHM, and PDF, with features such as typography customization, full-text search, offline reading, themes, text-to-speech, annotation, and file management. Their entry timeline before the index shows a sparse, irregular pattern from 2009 through 2026, with single entries in most months and gaps of several years. Traction leaders, all at 2 stars, are MingScribe, eupb-read, and inkweave.

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 16 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
