Full Text Databases

The vast majority of records (or “answers”) within the STN databases contain bibliographic information, sometimes an abstract, and sometimes drawings or images. Most do not contain full text information. For these files, STN will direct the user to an external website where the full text document can be purchased (see the Document Delivery section). For more information on any database mentioned, or to see the full range of databases, see the STN Database Summary Sheets homepage.

The FULLTEXT database cluster consists of all full text patent databases available through STN (also included in the PNTTEXT Cluster) and some non-patent full text databases. The following databases are included in the FULLTEXT cluster:[1]

Partial Text Databases

Almost all databases on STN which are not listed in the full text collections, above, will contain bibliographic data and sometimes document abstracts and/or representative drawings or figures.

A comprehensive list of the databases on STN, along with descriptions of their content, can be found via this list of STN database summary sheets.

Database Clusters

STN Database Clusters are groups of similar databases that have been bundled together by STN. These clusters can be searched as a shortcut allowing the user to search all files in the cluster simultaneously. Some clusters contain databases that cover similar subject areas, such as agriculture or toxicology. Others contain databases that share a similar feature; for example, the FULLTEXT cluster includes databases that contain the full text of journal articles and patents.

To search all of the databases in a cluster at once, the user should enter the "FILE" or "INDEX" command followed by the cluster name. Then the query may be entered. To display the list of clusters while online, a user should enter "HELP CLUSTER."[1]
