Drexel University Conclusions Adapted from: C.H. Montgomery and D.W. King, “Comparing Library and User Related Costs of Print and Electronic Journal Collections: A First Step Towards a Comprehensive Analysis,” D-Lib Magazine, October  Operational cost per use for print journals ($15) was much greater than for electronic journals ($0.45);  The highest cost per use ($30) was associated with bound journals, given the cost to house them and their relatively low use; Full-text database journals were used heavily and were cost effective (at less than $1 per use); Unit costs for publisher’s packages and aggregator journals were more cost-effective than individual subscriptions.

Medical Branch Library Muenster, Germany Conclusions Adapted from: Oliver Obst, “Patterns and Cost of Printed and Online Journal Usage,” Health Information and Libraries Journal For titles included in the study, users accessed the online version significantly more than the print version. The unit cost of an online usage was 5.38 times (18.68 € /3.47 €) less expensive than the unit cost of print journal usage.

II.Using Unit Cost Data for Management Decisions University of Virginia University of Connecticut Colorado Alliance of Research Libraries (CARL)

UVA Summary Special thanks to: Jim Self (UVa) Electronic journals provided by 26 publishers and aggregators cost about $2.3 million in fiscal year 2003, and there were 1.4 million recorded, yielding an average cost per article downloaded of roughly $1.64. Cost per article used ranged from $.07 to $17.92; the median publisher/aggregator cost per article use was slightly more than $1.00. Forty-nine major electronic reference databases cost approximately $550,000 annually. These 49 databases were searched about 1.05 million times last year, yielding a $0.52 per search cost. The most heavily used database was searched more than 270,000 times, at a per search cost of $0.08. An infrequently searched database had the highest per search cost ($16.68).

CARL Summary Special thanks to: George Machovec (CARL) Subscribing to 13 databases costs CARL about $600,000 a year. The databases are then offered to more than 100 libraries, 10 of which are Alliance members. Based on annual usage, each library in the state is assessed a share of the cost, with a $350 minimum. Colorado Alliance of Research Libraries’ 10 members used the 13 databases approximately 1.3 million times in a recent fiscal year, or 56% of the total state- wide use. Consequently, each CARL member paid about $0.25 for each use of these databases.

Conclusions Different libraries can expect to have different nonsubscription and unit costs per use for their electronic collections, even if licensing costs are similar. Electronic journal use data will become more reliable and is probably already more reliable than use data for print journals, allowing better unit cost comparisons among journal titles. Operating costs in the print environment typically exceeded subscription costs; in the pioneering Drexel study, nonsubscription costs ($0.45) represented only about 25% the total cost per use ($1.85) of electronic journals. Libraries still typically compute subscription cost per use, not total cost (i.e., subscription plus nonsubscription) cost per use.

Conclusions We can expect significantly lower operating costs in the electronic journal environment than we experienced in the print environment AND significantly more use, resulting in much lower unit costs per use. The data we now have available may raise some questions about our previous selection policies: Some journals whose prices seemed preposterous in the absence of cost per use data may seem (at least slightly) more reasonable in the context of cost per use. Conversely, some reasonably priced journals now seem expendable given their low-recorded use and unit cost per use.

III. MINES for Libraries™ U.S. Medical Libraries U.S. Main Libraries Ontario Council of University Libraries (OCUL)

MINES is a research methodology consisting of a web-based survey form and a sampling plan. MINES measures who is using electronic resources, where users are located at the time of use, and their purpose of use. MINES was adopted by the Association of Research Libraries (ARL) as part of the “New Measures” toolkit in May, MINES is different from other electronic resource usage measures that quantify total usage (e.g., COUNTER, EQUINOX, E-Metrics, ICOLC Guidelines, ISO and NISO standards) or measure how well a library makes electronic resources accessible (LibQual+ TM ). What is MINES?

Library User Survey

Purpose of Use By Location U.S. Medical Libraries 2003 – 2005 *83% of sponsored research usage occurred outside the library. 92% of this use took place on-campus. On-Campus, Not in the Library n = 15,948 In the Library n = 6,590 Off-Campus n = 4,852 Overall Use n = 27,390

Purpose of Use By Location U.S. Main Campus Libraries 2003 – 2005 *72% of sponsored research usage of electronic resources occurred outside the library; 83% took place on campus. On-Campus, Not in the Library n = 9,460 In the Library n = 9,733 Off-Campus n = 7,790 Overall Use n = 26,983

OCUL Scholars Portal Users by Purpose of Use In a sample of 20,300 electronic resources uses at OCUL libraries, there were four uses outside the library for each use in the library.
