This paper provides a snapshot of United States academic libraries in 2020 and explores longitudinal trends in staffing and expenditures for 1996 to 2020. The authors merged and analyzed academic library data from the National Center for Education Statistics from over 4,000 postsecondary institutions. Characteristics are explored by region and maps are provided. Total inflation-adjusted library expenditures have increased steadily for all regions from 1996 to 2020, including in the two major expenditure categories of staffing and collections. In the Northeast and West, averages are markedly higher in staffing and total expenditures than the other two regions.
