Government Documents, received under the Federal Depository Library Program, are organized using the SuDoc (Superintendent of Documents) Classification System. O'Neill Library receives approximately 42% of Depository items in paper, microfiche, CD-ROM, and electronic formats. Holmes will indicate the format of a particular item. Government Documents are located on the 1st floor of the O'Neill Library.
The SuDoc classification system is organized according to the agency that issues the publication. This guide gives an overview of the classification system, describes how to read a SuDoc number and describes how to locate the document in either paper or microfiche format. If you need assistance locating a government document, please contact Sarah Hogan (617-552-3306; hogansa@bc.edu).
