INTRODUCTION 



Scope This is a bibliography of the world literature on elec- 

 tron microscopy for the use of practicing electron microscopists. 

 We have attempted to include all papers that report or review 

 original research with or upon the electron microscope. Elec- 

 tron diffraction has been excluded, except for papers reporting 

 instrumentation adapting the electron microscope for these 

 studies, and for studies employing parallel diffraction and 

 microscopic examination of specimens. Papers describing other 

 types of microscopy not functioning with visible or ultra-vio- 

 let have been included. 



This first volume of a series of projected cumulations 

 of references published earlier on edge-notched cards contains 

 all references to papers published from 1950 through 1955 that 

 were issued on cards through June 1958. Not intended to super- 

 cede the references currently being published on cards, the 

 cumulations on pages, necessarily published after some delay 

 to allow the fullest reporting of the most recent year's ref- 

 erences, are a careful reworking of material published in 

 haste previously, in a compact format. 



Titles .The titles of papers are rendered in the language of 

 publication, except when that language is in a non-Roman alph- 

 bet or is a minor western European language. In these in- 

 stances the title has been translated into English and the 

 language of the original noted in parenthesis. The titles of 

 abstracts are followed by the designation: (Abstract) . 



Journals The titles of journals have been abbreviated accord- 

 ing to the style found first in reviewing the following sources 

 in the order listed: List of Periodicals Abstracted by Chemical 

 Abstracts (Columbus, Ohio), Current List of Medical Literature 

 (Washington, D.C.), and World List of Scientific Periodicals 

 (London, Butterworth) . 



References A reference consists of author (s) , title, and an 

 item number. The item number uniquely identifies a reference 

 in relation to every other reference in the volume, and is the 

 means of identifying the reference in the coauthor and subject 

 indexes. In addition, when the reference is to a book, the 

 place of publication, name of publisher, and year of publication 

 are supplied. When the reference is to a paper in a journal, 

 the abbreviated title of the journal is followed by the volume 

 number, inclusive paging, and month and year of publication: 

 36:813-5. 9/53.
