Policy and formulation

  • Use to record sources where you might reasonably expect to find an entry, but it's not there, for example:
    • Oxford DNB for dead British people
    • ULAN for artists
  • Take a broad approach to "might reasonably expect to find," that is, record a source that contains information about the entity, even if the entity is obscure
  • Precede additional $a's with a semicolon
  • Date dynamic sources
  • Tentative: Include dated VIAF searches
  • Since these are notes, it is permissible to render date in form: yyyy-mm-dd


675  Oxford DNB 
675  VIAF 2015-01-16; $a ULAN 2015-01-16
