Data, citations and reuse
Stable addresses for readers, applications and search engines.
The complete collection
The 310 records have canonical HTML pages, citations, scope and bilingual PDFs. Data distinguish a source period from an actual batch BUD and leave unavailable measurements null.
Citing a record
Record author/scientific editor, title, identifier, edition, canonical URL and access date. Retain the original source, its edition and locator separately.
Reuse scope
Free reading is not a blanket licence to republish all source material. Individual provenance and rights statements apply. Complete licensed publisher originals are not supplied, and an unanswered permission request is not represented as approval.
