F
F.The bibliographic abbreviation for folio: hence ‘F1 [title of work]’ means ‘the first folio edition of [that work]’, ‘F2 [title of work]’ means ‘the second folio edition of [that work]’, and so on. In Shakespeare studies ‘F1’ almost invariably means the Shakespeare Folio of 1623 (Mr William Shakespeares Comedies, Histories and Tragedies).
