The big news in the map world this week is a 17th-century map that was found in Aberdeen, Scotland, stuffed up a chimney to stop drafts. Discovered during renovations, the map was handed over to the National Library of Scotland, which found it to be in very bad shape: the 2.2×1.6-metre map, identified as work by the Dutch engraver Gerald Valck, was disintegrating, with pieces falling off every time it was moved. The Library’s restoration process is featured in an article in the winter 2016 issue of their magazine, Discover (direct PDF link), and in two videos about the map: one I’ve posted above, plus another, shorter video. You should take a look at them all: they present a fascinating look inside the conservation process. More coverage at Atlas Obscura, BBC News and Smithsonian.com.
