How are records in a results set sorted?
The default sort for references is by “accession number,” which is essentially the same as reverse-date: newest documents on top. You can resort a results set by author, document title, or reverse publication year. Substance records are default sorted by Registry Number, which means that the most recently reported substances – which usually have few or no references – are on top. It is more useful to re-sort by Number of References, which will bring the best-known substances to the top.
