How are subject headings and other key concepts indexed?
Librarians assign index terms to submissions using the “Alcohol and Other Drug (AOD) Thesaurus, Third Edition, 2000,” developed under the auspices of the National Institute on Alcohol and Alcoholism and SAMHSA’s Center for Substance Abuse Prevention (CSAP). Additional key concepts, such as Protocol numbers or the names of the CTPs involved in the study, are assigned by the CTN Librarians after careful review of the item. If you see an item that appears to be missing relevant terms, please contact the CTN Dissemination Librarians to suggest additional indexing.
