Practical guide and verification
Source facts come before formatting
An AMA formatter can order bibliographic elements, but it cannot reliably infer whether a page has named authors, an organization author, a publication date, journal volume/issue or a persistent identifier. Verify those details at the source.
Numbered citations require consistency
AMA commonly uses numbered references tied to the order of citation. Renumbering one source can affect later in-text numbers, so keep the manuscript and reference list synchronized rather than editing them independently.
Common mistake
Do not treat a website footer date or search-engine snippet as the publication date unless the source identifies it that way. Medical and scientific pages often distinguish publication, update and review dates.
