How we cite
We cite in APA style with DOI where available. Every page lists its sources in the Science Corner at the end. This list gathers all sources of the published pages and is generated automatically from them.
Status of the sources
Each entry has been cross-checked against a publisher or repository record (existence, authors, year, pages, DOI). That is not the same as a complete check of the content. We take figures from the originals only once we have read the source in full. How far a source has been checked is marked on each entry: “Entry checked” or “Full text checked”. The same information appears in the Science Corner of every page, there also as a ratio. How we work is described in the editorial process.
Reporting errors
If you find an error in a reference, write to us using the contact details in the imprint. We note corrections with a date in the change log of the affected page.
