1Bronson, R.J.: MeSH chemical headings and pharmacologic action.
In: Medical reference services quarterly. 16(1997) no.3, S.45-53.
Abstract: National Library of Medicine's Medical Subject Headings (MeSH) terms for chemical compounds are arranged in 2 trees: for chemical structures; and for pharmacological action. In 1996, indexing policy changes were implemented which affected chemical terminology in the pharmacological action tree. The change also led to the creation of a new field, Pharmacological Action (PA), in the MeSH Vocabulary File Database. Demonstrates practical searching of MEDLINE and related databases using the PA field

2Bronson, R.J.: NLM's new proximity searching.
In: Medical reference services quarterly. 15(1996) no.1, S.57-62.
Abstract: Reports the introduction of a new proximity searching capability to the NLM's ELHILL software in Mar 95. Searchers are now able to scan various fields in a citation for concepts contained within an individual sentence. The 3 proximity operators are: ADJ, NEAR and CONTAINS. At the time of writing, these operators are only available for searching MEDLINE and other ELHILL databases but not for PDQ or any of the TOXNET databases or data banks
3Bronson, R.J.: More NLM proximity searching hints.
In: Medical reference services quarterly. 15(1996) no.3, S.49-56.
Abstract: Describes additional proximity searching operators: clusters; contains and nesting
4Bronson, R.J.: Creative ways to locate MeSH subheading information.
In: Medical reference services quarterly. 13(1994) no.1, S.73-80.
Abstract: Locating notes about MeSH subheadings can be one of the most difficult aspects of MEDLINE searching. When used with MeSH, subheadings serve to limit or define the focus of a heading. NLM indexers, staff members who enter the MeSH indexing into the database, use subheadings freely. They do follow indexing conventions and searchers need to be aware of how to obtain basic subheading information to assist in search formulation. There are a number of methods which may be used in order to view subheading use notes
5Bronson, R.J.: NLM's MeSH vocabulary file.
In: Medical reference services quarterly. 11(1992) no.2, S.47-57.
Abstract: The following printed publications list the MeSH headings: the annotated alphabetic list, the tree structures, the permuted MeSH, the medical subject headings supplementary chemical records, and the 'black and white MeSH', which is shipped as part of an Index Medicus subscription. An online database is available which combines the features of these publications and can provide useful information to searchers of NLM's computer databases. Describes the scope, searching strategies and special features of the online MeSH vocabulary file
