Frequently Asked Questions
Q: What is a concept code?
A: Concept codes are five-digit codes representing broad subject areas in the life sciences. A definition (concept heading) of the code follows the numeric code. You may search by code or heading.
You can perform a search on concept codes in the "Concept Code/Heading" field on the General Search page or by using the field tag CC on the Advanced Search page. Use the Concept Code Search Aid to find codes to add to your search.
Q: What information is in the Geopolitical Locations (GE) field?
A: The Geopolitical Locations (GE) field is used for any land, water body or man-made structure that is the focus of an indexed document. GE distinguishes ecological descriptors (e.g., rainforest, ocean, desert) from geopolitical descriptors (e.g., Atlantic Ocean, Great Basin, Mt. St. Helens). Geopolitical terms are captured from the title, abstract and text of an item.
Up to 20 separate GE items are created in any single indexing item. If more than 20 individual geopolitical terms are provided in an indexed document, the terms are grouped into specific categories to be indexed as key terms. For example, if 25 U.S. states are listed, “USA” is indexed as the GE key term instead of the specific 25 states.

This includes: gene symbols, gene families and gene clusters. Gene name terms are captured from the title, abstract and text. The term “gene” by itself or a non-specific gene description (tumor suppressor genes, early immediate genes, and candidate genes) is placed within the Chemicals and Biochemicals (CB) Term Type.
Q: What information is in the Sequence (SQ) field?
A: The Sequence (SQ) field includes databank accession numbers for proteins and nucleic acids and associated relational data including the data repository name.
Q: What information is in the Chemicals and Biochemicals (CH) field?
A: The Chemicals and Biochemicals (CB) field is used for all relevant terms referring to chemicals or biochemicals studied in an indexed document. CB terms are captured from the title, abstract and text of an indexing item. Up to 20 separate CB items may be created in any single indexing item. If more than 20 individual chemical or biochemical terms are provided in an indexed document, the terms are grouped into specific categories to be indexed as key terms (e.g., heavy metal, insecticide).
Q: How are author names formatted in Biological Abstracts?
A: Author names are presented exactly as they appear in the source publication,
including full first names. However, it is still advisable to search for an
author by truncating after the first initial when possible. John E. Chandler may
be represented in the database as Chandler, J. E. or Chandler, John, or Chandler
John E. Moreover, he may have published under any of those names. In this
example, it is advisable to search for Chandler as follows:
AU = Chandler J*
Please see Biological Abstracts Help within the product for more information.

Q: What is the BIOSIS Digital Archive for Biological Abstracts and BIOSIS Previews?
A: These new backfiles contain the digitized content of the print Biological Abstracts volumes 1-49, 1926-1968. These volumes have been digitized and re-indexed to match current BIOSIS indexing. The bibliographic data (authors, titles, source data, abstracts) found in Archive records are presented largely as published in the original print volumes.
Q: Have the abstract numbers in the print volumes been preserved in the Archive, and are they searchable?
A: Yes, they have been preserved and are searchable. The abstract number, in combination with the year of BA publication and the BA volume number is the basis of the accession number in the digitized file. For example, accession number PREV19290300006236 is abstract number 6236 from BA Volume 3, published in 1929. Accession numbers have the prefix PREV in BIOSIS Previews or BACD in Biological Abstracts. They can be searched in the Identifying Codes field.
Q: Are there any differences that may affect my search strategy when searching the Archive in conjunction with the 1969+ file?
A: For the most part, searching all date segments is seamless, but there are several points that should be considered in your search strategy.
