The Academic Libraries Surveys in 2002 and 2004 were studies that are part of the Academic Libraries Survey (ALS) program; public-use program data are available since 1996 at https://nces.ed.gov/surveys/libraries/aca_data.asp. ALS:2002/2004 (https://nces.ed.gov/surveys/libraries/academic.asp) are cross-sectional surveys that summarize services, staff, collections, and expenditures of academic libraries in degree-granting postsecondary institutions in the 50 states and the District of Columbia. These studies provide information pertinent to libraries at degree-granting postsecondary educational institutions.
