┆The National Art Slide Library was a resource held at the Victoria and Albert Museum in London. It was a lending library specifically for slides of art, applied art and architectural subjects which could be borrowed by individuals for research or to illustrate lectures. The library was moved to Leicester Polytechnic in the 1990s and fell out of use due to the rise of Power Point and similar computer technology, which ended the use of slide projectors during lectures. The slides were moved to DMU's Special Collections.
"Growing from modest beginnings in 1898, the collection was reorganised after the Second World War and now totals more than half a million slides. These are listed in a catalogue on site and in printed catalogues and lists which are available to libraries and individuals; slides are retrieved by accession number from electrically-operated storage units. Slides may be borrowed free of charge, in person or by post, by any resident of the United Kingdom." - from "The National Art Slide Library at the Victoria and Albert Museum", by Bertie Maxwell, Art Libraries Journal, Volume 2, issue 4, Winter 1977, pp. 31-36.
