Searching the Concept Codes Field

Enter concept codes to search the Concept Code(s) field within a record.

Concept codes are five-digit codes representing broad subject areas in the life sciences as discussed in the source document, such as phylum, class, or family. A code is assigned for each organism type. A definition (concept heading) of the code follows the numeric code. For example:

Broad Concept Heading	Concept Code	Concept Heading
Behavioral biology	07002	general and comparative behavior
	07003	animal behavior
	07004	human behavior

You may search this field by code or heading.

Did You Know ... Groups of related concept codes are arranged under broad concept headings. For example, the concept heading for Toxicology is comprised of Concept Codes 22501-22508 and can be searched with a wildcard. For example: 225*
