The ISSN (International Standard Serial Number) searches for periodical publications such as journals and electronic publications. If a journal has both a print ISSN and an electronic ISSN, then both display in the Full Record. The format is four numbers, a hyphen (-), three numbers, and then a check character that may be a number or X.

index

IS=ISBN

Searches the ISBN field within a record.

The ISBN (International Standard Book Number) searches for books. It is a unique machine-readable identifier that marks a book unmistakably. The format is a 10-digit number that contains 3 hyphens (-). The last digit is a check character, which may be a number or an X. The position of the hyphens can vary for each ISBN identifier.

index

PMID=PubMed ID

Searches the PubMed ID field within a record.

index

PU=Publisher

Searches the Source Published field within a record. You must combine this field tag with another field tag using the AND or NOT Boolean operator.

Example: TS=cell growth AND PY=2007

When entering a range of years, restrict your search to five years or less; otherwise, processing slows down and the product returns too many unproductive results.
