On the National Library of Scotland’s blog, a look at steps taken to conserve and repair two damaged 19th-century maps. “These case studies show some of the treatment options available for large maps, and demonstrate the challenging decisions that have to be made in order to care for the Library’s collections in their entirety. The principles at the heart of every conservation intervention are reversibility and retreatability, which ensure that we can always return to an object in the future if circumstances change.” [via]
In 2009 it was announced that map collector David Rumsey, whose eponymous website has been a must-visit for any map aficionado, would be donating his collection of 150,000 maps, plus digital copies, to Stanford University. Preparations to receive Rumsey’s collection began last summer. Now the David Rumsey Map Center is set to open—an event that will be marked with a reception on 19 April, the opening of an exhibition called A Universe of Maps: Opening the David Rumsey Map Center, and a series of presentations and workshops over the following two days. Speakers include Anne Knowles, Susan Schulten and Chet Van Duzer, among others, as well as Rumsey himself. [via]
The Descriptive Cataloging of Rare Materials (Cartographic), available as a PDF file (direct link), “provides instructions for cataloging rare cartographic materials, that is, cartographic materials of any age or type of production receiving special treatment within a repository.” This is a substantial, technical document (364 pages), mainly of interest to librarians with rare and old maps under their care.
With an increased focus on the security of rare cartographic materials, DCRM(C) addresses the need for a stand-alone set of rules that covers the treatment of atlases, maps, and globes, both printed and manuscript, including the analysis of cartographic works in books or other resources, and can be used by any institution that houses these materials. The creation of a standard eliminates the need for each institution to develop extensive local practices for the treatment of rare cartographic works, and makes it possible for institutions with smaller collections to benefit from both the sophisticated tradition of rare materials cataloging and the awareness of the cartographic community of the particular qualities of our materials.
The Michigan State University Map Library now has on display three copper plates used to make the 1912 USGS topographic map of the Lansing, Michigan area. “From the 1880s to the 1950s, the U.S. Geological Survey used engraved copper plates in the process of printing topographic and geographic quadrangle maps. Copper alloy engraving plates were inscribed with a mirror image of the points, contour lines, symbols, and text that constitute a topographic map. Each plate was inscribed with details for a single color of ink.” [via]
