Selection for BIOSIS databases occurs at two levels: first at the journal, or source, level where journals are evaluated and accepted for coverage and then, as issues of a journal are received, at the journal issue level, where items within an issue are chosen for inclusion.At the journal level, the BIOSIS editorial group evaluates a title for coverage on three aspects of the publication's attributes: Subject; Editorial Content and Publication Attributes; and Geographic Origin and Scope.Once a source journal is accepted for coverage, guidelines are established for item selection based on the content of that source. Many sources are 'cover-to-cover' meaning that nearly every item from the journal will be included in BIOSIS coverage. Other sources are ‘non-cover-to-cover' where certain sections or types of items are not selected. At the issue, or item, level certain items are excluded.More information on Biosis Previews's selection policy can be found at http://jisc-collections.ac.uk/Catalogue/biosis-policy/
