Separate credit discovery from credit verification. A large database can reveal possible titles, but the finished work, official credits, distributor material, guild records, or a reputable archive should settle role and edition questions. Track alternate titles, release territories, episode numbers, and whether a credit was on-screen, uncredited, archival, or rumored. Do not count an announced project as released work. A filmography is most useful when a reader can tell what was performed, when it became public, and which record supports the entry.
