This blog from the National Library of Scotland keeps you up to date with news on the Bartholomew Archive, a remarkable record of the Edinburgh-based firm of map engravers, printers and publishers, John Bartholomew & Son Ltd. It is one of the most extensive cartographic archives available for research in a public institution. Members of the Bartholomew family were engaged in map-making from the first known map engraving work of George Bartholomew in 1825. John Bartholomew junior started printing operations before 1870. For more than a century afterwards the Bartholomew firm specialised in high-quality map production.
