Abstract Expenditures for Library Resources in Academic Health Sciences Libraries Carlene Drake Director, University Libraries, Loma Linda University, Loma Linda, CA Introduction Serials Spending for serials in the libraries studied increased 46%. Spending at LLU for serials increased 55%. Spending for serials had the most consistent pattern across all libraries. Overall AAHSL spending for serials across the 10 years increased 28%. All Resources The years analyzed were 1996 through Spending during these 10 years for all resources in the libraries studied increased 47%. Spending for all library resources at LLU increased 59%. Total spending for all AAHSL libraries increased 38%. Five academic health sciences centers with similar demographics and program offerings to Loma Linda University (LLU) were selected. The libraries are all associated with medium-sized academic health science centers. The Association of American Medical Colleges (AAMC) Medical School Profile Report system was used to help select the libraries. A comparison of the data reported to the Association of Academic Health Science Libraries (AAHSL) annual statistics in the category of Expenditures- Information Resources/Collection Development was analyzed. Trends in increases and decreases for specific resources, monographs versus serials versus electronic resources, over the last ten year were examined and charted. Loma Linda University is a private Academic Health Science center with programs in Dentistry, Medicine, Nursing, Allied Health, Public Health, Pharmacy, Social Work, Marriage and Family Therapy, Psychology, and Natural Sciences. As our budget for resources has seen significant change over the last ten years, we wanted to see if similar types of changes were occurring in other private health science centers. The online Association of Medical Colleges Medical School Profile Report system was used to help select the libraries. The five libraries selected were: Jefferson University, Creighton, Oregon Health Sciences, Temple, and Rush. All of these libraries serve private academic health science centers. The medical schools in these libraries were similar in student enrollment to LLU and they all serve programs in addition to medicine. The total number of enrolled students in all programs of the schools was not always similar. Conclusion Between 1996 and 2005 spending for library resources in the libraries studied increased 47%. As overall spending increased, there was a definite shift away from monographs to serials and databases. The AAHSL statistics did not begin reporting database/electronic spending until Prior to that access to External Information was reported as part of total collection spending. The total number of monographs held by AAHSL libraries decreased 3.5% and the total number of serial titles as reported increased 69%. Among the libraries analyzed, the percentage of spending for monographs decreased more than the AAHSL average and percentage of spending for serials and databases increased more that the AAHSL average. Collection expenditures for serials at LLU were typical of the changes seen in other academic health science center libraries over the years analyzed. LLU monographic spending has not decreased at the same rate as the libraries analyzed, however, it has decreased more than for AAHSL libraries total. Database spending at LLU increased at a higher rate than either the group analyzed or AAHSL libraries as a whole. Monographs Total monograph spending for all libraries selected decreased 37%. Of the five libraries selected, two actually increased their reported spending for monographs, one 23% and one 43%; while one library actually decreased monographic spending 69%. LLU monographic spending decreased 18%. Total monographic spending for all AAHSL libraries increased 3%. Databases The first year the AAHSL statistics reported electronic resources as a separate figure was This is where database costs were reported as libraries began to license and purchase databases, however, e-books and e-journals were part of this figure until This figure has changed over the time frame above and now represents databases. Between 1999 and 2005 database/electronic resource spending in the libraries studied increased 63%. Database/electronic resource spending at LLU increased 84%. Overall AAHSL spending for databases/electronic resources increased 51%.
