University & Library Total Expenditures (formerly known as the E&G Survey) data are used to produce charts and tables showing what fractions of total university spending have gone towards the research library.

Since 2003, this has not been gathered in a separate survey; instead IPEDS data regarding total university expenditures have been used with the Total Library Expenditures data from the ARL Statistics to produce charts and tables showing Total Library Expenditures as a Percentage of Total University Expenditures.
