How the shelf is organized.

Titles, authors, editions, publication dates, ISBNs, covers, and publisher descriptions may originate from Open Library, Google Books, publishers, retailers, authors, or direct catalog maintenance. Edition records are grouped into a work when they represent the same underlying book.

A trope tag describes a meaningful character, relationship, setting, or plot pattern. Tags can be editorial, assisted by a language model, or supported by community votes. The site favors reader-useful tags over every incidental plot detail. Automated tags are candidates, not claims of perfect literary interpretation.

Heat is represented on a five-step scale from Sweet through Explicit. The scale considers what appears on the page, how directly it is described, and how frequently intimate scenes occur. When several sources disagree, community evidence takes priority, followed by editorial and assisted classifications.

Warnings are split into Mentioned, On the page, and Central theme. Severity describes narrative presence, not moral weight. A warning can be incomplete or disputed, especially for newly added books. Readers should use it as guidance rather than a substitute for publisher or specialist resources.

Similar-book pages begin with shared tropes and then use catalog quality and popularity signals to order credible candidates. Personalized recommendations also consider a reader's stated favorites, heat range, and hard limits. Paid placement does not alter these rankings.

Some taxonomy introductions and catalog classifications are drafted with assisted tools under detailed editorial rules. They avoid claims about specific books unless supported by catalog data. High-traffic pages are reviewed and improved as reader feedback and search demand identify priorities.

Catalog data changes as better evidence arrives. If a tag, warning, author record, series order, or description appears wrong, use the correction process. Submissions are reviewed before editorial records are changed.
