This search allows the user to supply terms to search the abstract fields of the citations. Not all citations contain abstracts. This search can be useful if the term supplied does not exist as a keyword (e.g., \"policy\") or if a keyword has not been assigned to a citation. Some keywords have been added more recently than others and were not retrospectively assigned to the then existing citations.

What is an Author Search?
This search performs a truncated search on a part of an author's name. Last name (or part thereof) first, then first name (or part thereof), if known. Separate last name, first name with a comma, space. This search retrieves citations and abstracts from all authors whose names begin with the letters supplied.
What is an Author List?
Choose one author from the complete author list. This search retrieves all citations by that author regardless of authoring status, i.e, principal or secondary authorship. Check for multiple occurences of the same author due to the use or lack of middle initials and hyphenated names.
What is a Source List?
Choose a source (e.g., a specific journal, monograph, conference names, or corporate body or institutional name) from the list of citation sources. This search retrieves all citations published by the selected source.

What is a Keyword Search?
Choose one or more keywords from an alphabetical list and retrieve all citations that were assigned the specified keywords. Keywords (subject topics) are assigned by NLS staff to group the citations by topic. Because new keywords may be added to the list and assignment is somewhat subjective, this search may return a different list of citations than the abstract search. You may use this list to browse the complete keyword list. This form may take up to 3 minutes to load.
