Searches the ISSN field within a record.

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.


Searches for organizations and institutions in the Addresses field within a record.

PY=Year Published

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.

Example: TS=cell growth AND PY=(2008-2010)

SO=Publication Name

Searches for publication names in the Source field within a record. The product retrieves all source titles within a product database (for example, journal titles and/or book titles if the product includes books).
