CLUSTER BOOK-EPUB-HIGHLIGHTS · 11 ENTRIES · EARLIEST ENTRY 2021-10-27

Self-hosted e-book readers

This cluster comprises e-book readers that sync reading progress, highlights, and notes across devices via a personal or self-hosted server, typically supporting EPUB, PDF, and CBZ formats. Dated entries before the index start appear infrequently, with multi-year gaps between 2013-07, 2017-08, 2021-10, 2024-04, and 2026-05, showing a sparse and irregular entry pattern. All traction leaders (Liseur, author-today-read, Registrum) show zero stars, indicating minimal observable activity.

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