To restrict a search to one of the previous
data elements, use the specific commands
of your search system.
The data elements can be grouped into
three broad categories:
S o u rce Information: Journal, Biblio-
graphic Information, Publication Ye a r,
CODEN, Document Type and Language
Author Information: Author and Author
S ubject I nfor ma tion : Ti tle , Added
Keywords, Abstract, Concept Codes, Bio-
systematic Codes and Super Ta x o n o m i c
Any meaningful word or phrase can be
searched in BIOSIS Previews, with or with-
out specifying the data elements to be
searched. Or, you can use data elements as
your key to a successful search. These data
elements can be searched in any combina-
tion to suit your needs. For example, if
your search focuses on a specific type of in-
formation such as Author or Journal Name,
you may want to limit specific search terms
to the particular data element containing
only that information. However, when
s e a rching a particular subject, it would be
wise to consider all the subject data ele-
ments in your sea rch, especially Ti t l e ,
