cates were removed, yielding a total of 4,044 citations. The committee also searched for literature on illnesses in Gulf War veterans and related concerns. In August 1999, the same search strategies were used to identify any citations on newly published literature pertaining to the committee’s review. This update retrieved 274 citations, which were added to the committee’s databases.
Since online databases were developed in the mid-1960s, few offer retrospective coverage. To identify pre-1960s literature, the committee staff examined volumes of Index Medicus. Additionally, staff and committee members examined reference lists of major review articles and books for relevant citations; extensive reference lists were provided by several sources including the ATSDR Toxicological Profile on Uranium and recent reports by RAND. The study also accessed the TOXNET factual databases available through the National Library of Medicine and the Cochrane Collaboration database. In addition to the above sources, input was received from veterans, interested persons, committee members, and speakers at committee meetings. The committee also examined more recently published studies that it identified.
LITERATURE COLLECTION, DISSEMINATION, AND ANALYSIS
All retrieved citations were entered into bibliographic databases, which at the end of the study contained 6,249 references to abstracts, journal articles, books, military and civilian reports, dissertations, and conference proceedings relating to the agents and to the Gulf War. Staff and committee members reviewed the citations and abstracts for relevance to the committee’s task. Acquiring the full text of the published literature involved accessing the collections of the National Library of Medicine (NLM), the National Institutes of Health Library, the Himmelfarb Health Sciences Library of the George Washington University, and the National Research Council (NRC) Library, as well as use of the NRC’s interlibrary loan service. Documents were also ordered from the National Technical Information Service and other sources. The committee’s work greatly benefited from access to the NLM’s Docline document delivery service. Citations and abstracts from foreign language journals were reviewed, and a number of the most relevant foreign language articles were translated into English.
The committee divided itself into four working groups (PB, DU, vaccines, sarin–cyclosarin) that were responsible for identifying, reviewing, and analyzing the relevant literature. The work of each of the working groups was also reviewed by committee members from other working groups, and was presented and discussed thoroughly by the entire committee at each stage of the writing and analysis.
