The Bartholomew Archive 
The firm's extensive archive contains business records (principally 1870s-1980s), including manuscripts, maps, photographs, copper plates, and glass plate negatives. Bartholomew was a jobbing printer, so the archive is an invaluable source for publishing and social history, as well as cartography.
In 2007, the National Library of Scotland (NLS) announced that the John R Murray Charitable Trust offered funding of £220,000 over three years (2007-2010) to enable some of the Bartholomew Archive to become more accessible.
The remarkable archive of the Bartholomew mapmaking firm came to NLS in installments over many years, but particularly from 1985 when control passed to HarperCollins (part of News International) from Reader's Digest which had bought the firm in 1980. The largest part of the collection was handed over in 1995 when the Edinburgh operation moved to Bishopbriggs.
