Searching the Taxonomic Data Field

The Taxonomic Data table in records is divided into the following categories:

Super Taxa 

Taxonomic terms that classify organisms, including microorganisms, above the genus/species level. Taxa are presented in order from lowest to highest. To see a list of Super Taxa terms, click this link.

Taxa Notes 

Common names of broad groups of organisms and microorganisms discussed in the source document.

Organism Classifier [Biosystematic Code] 

Controlled term for the taxonomic rank of family. Each organism classifier is accompanied by a Biosystematic Code, which positions the classifier in the taxonomic hierarchy. 

Biosystematic codes are assigned to all controlled taxonomic terms--super taxa as well as organism classifiers. You can access a hierarchical list of taxonomic terms and their biosystematic codes by selecting Taxonomic Data on the Basic Search page and then clicking the Select from List link. 

The code may be followed by an asterisk (*), which indicates the reporting of a new taxon. In some instances, the asterisk may be replaced with -NEW.

Organism Name 

The formal scientific name (genus and species) or informal common name of an organism. This field may also include names of cell lines mentioned in the source document. 

Organism names are available in records from 1925 to 1968 and from 1993 to the present. In records between 1969 and 1992, organism names may be found in the Miscellaneous Descriptors field.

Variant 

A variant name for the organism. The variant may be a corrected spelling (from the author) or another common or species name. This field is available in records from 1993 to the present.

Details 

Other information such as gender of the organism, its developmental stage, and its role. It may also contain a fossil indicator and whether the organism is a new taxon and its type. This field is available in records from 1993 to the present.
