Many collections are digitised entirely from microfilm, at least initially: for example, the Times Digital Archive was digitised from microfilm up to 1985 but now The Times’ digital PDF copy of each issue can be used. For the British Library collections, from the early 1940s to 2010 the usual method of preserving newspapers was microfilming and approximately 30% of the newspaper collection was microfilmed during this time. Delpher’s policy is to digitise from paper, unless microfilm of an acceptable quality is available. Trove has begun to digitise from physical copies, particularly for titles that have not previously been microfilmed. Microfilm digitisation has led to the majority of newspapers being digitised in greyscale.
