History and Preservation

Abstract

Peter Hirtle writes about Atherton Seidell and the photoduplication of library material (J Am Soc Inf Sci 1989 Nov;40(6):424-31). Collection development policies in medical rare book collections are discussed by Christopher Hoolihan (Collection Management 1989;11(3 /4): 16779). Robert Gaskell examines the errata leaf of Harvey's De Motu Cordis of 1628 (Book Collector 1989; 38(1):60-5). Although less frequently than in the past, portraits are still being commissioned, and Imogen Sheeran offers practical advice (Br Med J 1989 Jul 1; 299(6690):37-9).
