Not everything here is ours, and the notice above does not claim it. The material below belongs to its makers or is in the public domain, and stays under the license its own source states.

Images from open collections

191 prints, paintings, botanical plates, pages of old books, early photographs and photographs of museum objects, each under the rights statement read on its host’s own record. Each is captioned with its museum or library where it appears, and listed image by image on Images from open collections.

Photographs from Wikimedia Commons

320 photographs and drawings in the material galleries and the home page’s mosaic, each used under the license stated on its own Commons page and credited under the photograph with its author and license; the full list is Photographs of the materials.

3D models, textures and light maps

Facts and data

Plain facts, such as a boiling point, a CAS number or the year a perfume was launched, are not ours to license, and quoted source text belongs to its authors. Every fact on a record carries its source, or the basis it rests on, beside it; 720 sources are on file, and the evidence register lists the claims the pages make with their sources. The databases most used:

  • Wikidata (Wikimedia Foundation): names, dates, places and identifiers on the records, each cited with the date it was read; its structured data is released under CC0 1.0.
  • PubChem (National Center for Biotechnology Information, U.S. National Library of Medicine): the molecules’ identities, weights and computed 3D conformers, credited with each compound number on its page (60 compound records on file).
  • GBIF Secretariat (2023). GBIF Backbone Taxonomy. doi.org/10.15468/39omei, CC BY 4.0: the accepted names of the plants.

Typefaces and software

  • Bodoni Moda, Archivo and IBM Plex Mono, with a small Greek-letter subset of Noto Sans, self-hosted, under the SIL Open Font License (Bodoni Moda, Archivo, IBM Plex Mono, Noto Sans); IM Fell English (SIL Open Font License) is lettered into some renders.
  • three.js (MIT license) draws the 3D viewer and the realtime plates; its notice is in licenses.txt.
