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, cite sources consulted that might have included the entity, even if the entity is obscure (for example, Benezit for an unidentified engraver)
  • Precede additional ǂa's with a semicolon
  • Give view date of dynamic resources
  • Since these are notes, it is permissible to render date in form: yyyy-mm-dd
  • In general, do not cite VIAF, unless the person's absence is significant. Apply cataloger's judgment.
  • With dynamic sources, such as Wikipedia or VIAF, always include a date viewed or searched, so the note doesn't become incorrect in the future.
