Electron Microscopy

A bibliography of world literature on all phases of electron microscopy is in the process of being issued on Keysort cards $(3.5″×7.5″)$ by the New York Society of Electron Microscopists. The first issue, covering the years 1950, 1951, and 1952 (approximately 700 cards), is now available, and plans have been announced for the early publication of material for 1953 and for quarterly publications on current literature thereafter. Articles containing multiple subjects can be located immediately by each subject as well as by author, according to the Society, and no order of filing is necessary for the cards because they are selected by needle.
