Series, works, publication data and the reading-order backbone contain information from the Internet Speculative Fiction Database, used under the Creative Commons Attribution 4.0 license. Records are edited and re-organized by Loreful; errors are ours, not ISFDB's.

Author biographies and some series, work and universe descriptions contain text from Wikipedia, used under the Creative Commons Attribution-ShareAlike 4.0 license. A credit appears beside each excerpt.

Universe entities and cross-database identifiers come from Wikidata (CC0); genres blend Wikidata with ISFDB tag data (CC BY 4.0, credited above); edition records and cover imagery from Open Library.

Chronological and recommended orders marked ✦ are written by the Loreful team, with a rationale published on every one.

Cover thumbnails appear for identification, credited to their publishers. A rights holder can request removal at any time.
