2001 CANCERLIT Reload News

CANCERLIT Reloaded to Reflect 2001 Vocabulary
The National Institute for Health (NIH) has completed the annual vocabulary maintenance for the 2001 reload of CANCERLIT.  For this reload, the following changes have occurred.

New Fields
Comments CM [for display only]
The Comments (CM) field contains Comments as they are entered into MEDLINE from the original document. 

Gene Symbol GS [Phrase Indexed]
The Gene Symbols (GS) field contains Gene Symbols as they are entered into CANCERLIT in the original document. They often, but not always, conform to standardized human gene nomenclature. Ignore super or sub-scripts in entry of a gene symbol: psub 120 would be entered p120. Beginning in 1996, data will no longer be added to this field.

Gene Symbol Word (GW) [Word Indexed] DOES NOT DISPLAY
The Gene Word (GW) field contains individual words from the Gene Symbol (GS) field.

Molecular Sequence (MS) [Phrase Indexed]
The Molecular Sequence (MS) field contains an organizational acronym and the unique identifier that organization has applied to a molecular sequence.  The acronym appears first followed by a hyphen and the unique identifier, as in genbank-60485.

Personal Name as Subject Heading (PN) [Phrase Indexed]
If an article is an interview, an obituary, or discusses a well-known person, that person's name will appear in the Personal Name As Subject (PN) field.  The format for the Personal Name field is the same as that for the Author field—last name and initials, as in Haddow A.  Enter a last name and one initial, if known.

PubMed Identifier (PM) [Phrase Indexed]
The PubMed Identifier (PM) field contains the PubMed number first assigned by NLM. This number is another unique identifier of the records.

CAS Registry Number (RW) [Word Indexed] DOES NOT DISPLAY
The Registry Word (RW) field contains single words from the Registry Number (RN) field and is used to search portions of chemical names.

Deleted Field
With the 2001 reload of the CANCERLIT database, the ISBN (IB) field has been eliminated.

Publication Type
The 2001 reload of CANCERLIT introduces three new Publication Types.

And with this reload, seven Publication Types have been eliminated: Government Report, Meeting Abstracts, Meeting Paper, Monograph, Non-government Report, Special Publication, and Thesis.
