Because of space limitations references to individual works which contain the required information are limited to a few outstanding or unusual items. THE PRIMARY LITERATURE The most important source of information is the primary literature. It consists mainly of the articles published in periodicals and of papers presented at conferences. New discoveries are first reported in the primary literature. It is therefore a major source of current information. Peer review and editorial scrutiny prior to publication of an article are imposed to ensure that the article passes a standard of quality. Most engineers are familiar with a few publications but are not aware of the extent of the total production of primary literature. Engineering Index known as Compendex in its electronic version alone abstracts material from thousands of periodicals and conferences. Handbooks and encyclopedias are part of the secondary literature. They are derived from primary sources and make frequent references to periodicals. Handbooks and encyclopedias are arranged to present related materials in an organized fashion and provide quick access to
