Over time
Gutenberg's catalogue has no publication dates, so its works are placed by the earliest author's birth decade. DTA and Wikisource works are placed by publication decade.

How the list was built
- Project Gutenberg: every English or German text in the PG catalogue (October 2026), scored on LoC subject headings and LoC classes QK/QL (2 points each), PG bookshelves (1–2), LoC classes QH and G (1) and title keywords (1). Works scoring below 2 and works catalogued as fiction are left out.
- Deutsches Textarchiv: the genres Reiseliteratur, Zoologie, Biologie and Geologie in full. Geographie is split by title: titles naming a journey count as travel, the rest as natural history.
- Wikisource (German): the categories Reisebericht, Zoologie (with Entomologie, Ichthyologie, Malakologie, Ornithologie), Botanik, Mykologie and Biologie, without encyclopedia entries. Most entries are magazine articles, many from Die Gartenlaube.
- EcoCor: the 16 of its 213 texts that are natural history or travel writing rather than fiction, labelled by an LLM and checked by hand. Each links to EcoCor's plant and animal annotations.
- Places come from LoC subject headings (Gutenberg), or from the title and description, read by an LLM (qwen38-27b on Uni Passau's innkube cluster). They were geocoded with OpenStreetMap's Nominatim. Broad regions such as "Africa, Central" or "Orient" sit at an approximate centre.
- Keywords were written by the same LLM from each work's title, author, date and subjects. They are a reading aid and can be wrong.
- Works found in more than one library are listed in each and tagged "also in".
