The Cost and Useof
Electronic and PrintJournal Collections
Conference on Libraries in the Digital Age (LIDA)May 28 - June 1, 2007Dubrovnic, Croatia
Donald W. King, Distinguished Research ProfessorUniversity of North Carolina at Chapel HillSchool of Information and Library Science
2
Topics of Talk
• Trends in the use of library collections– Focus on academic libraries– Emphasis on science faculty and staffs– Information-seeking patterns as context
• Cost of print and electronic collections– Bottom-up approach– Considering all resources applied– 25-year life cycle
• An indicator of the return-on-investment– Contingent valuation approach
3
Overview
• Sources of information used by scientists, engineers and medical professionals
• Reasons that professionals choose the sources that they do
• Importance of professionals’ time and effort in making choices
• Scholarly journals continue to be the principle source of needed information
• Trends in reading patterns over 30 years
4
Tenopir & King Survey Data• Surveys of 30,000+ scientists, engineers, social scientists,
medical and other professionals in many settings• Two NSF-sponsored national surveys (King Research 1977,
1984)• 26 surveys in organizations served by 84 special libraries (King
Research with Griffiths 1981-1995)• 12 surveys of faculty and students (U. of Tennessee and C.
Tenopir 1993-2006)• 6 surveys society member & journal subscribers (King Research
1977-1983, U. of Tennessee and C. Tenopir 2003-2006)• Current IMLS study with transaction log analysis (U. of
Tennessee & University College London, CIBER 2005-07)• 6,000 national household telephone surveys (University of
North Carolina, University of Pittsburgh)
5
Question: What sources did you usefor the last substantive piece of information you used for work? (n=469)
6
Questions from National Household Telephone Survey
• Over 200 interviews involve scientists or researchers– Do you ever read professional trade or
scholarly journals?
– From how many…do you read?
– Was the last article you read from a print or electronic version?
– Where did you obtain the last journal article you read?
– For what professional field is this last journal read?
7
Many Ways to Identify Articles
• Browsing through print or electronic journals (mostly for current awareness)
• Searching in search engines in bibliographic and e-journal databases (mostly for research and writing)
• Follow-up of citations in journals and other publications
• Recommendations from colleagues, etc.• Other (e.g., alerts, preprint services, etc.)

Reasons for Shift to Reading from the Library Collection
• Decrease in personal subscriptions
• More reading of articles identified by online bibliographic searches
• Electronic collections have broadened access to articles

Electronic Collection Contribution
• Personal subscriptions - 90% print• Library collections
– 80% electronic– Broadens journal availability– Saves readers about 20 hours per year
• Breadth of reading has increased– Read from about 13 journals in 1977– Over twice that amount now
• Age of article is a factor

King Bottom-up Library Cost Studies
• 40 public libraries (King Research with Griffiths, 1985-1992)
• 26 special libraries (King Research with Griffiths, 1984-1993)
• 11 academic libraries (University of Pittsburgh with Aerni, Drexel University with Montgomery, 9 other universities — JSTOR with Schonfeld, 2000-2004)
23

24
Life-Cycle Cost per Title
Electronic collection — $180 per title
Print collection — $580 per titleCurrent collection — $190 per
titleBackfile collection — $390 per
title
25
Annual Cost Per Reading
• Compare the Unit Cost of Services– Electronic - $3.00 per reading– Current Periodicals - $13.60 per reading– Bound Backfiles - $15.60 per reading– ILL - $8.40 per item– ILB - $12.60 per item
Life Cycle Cost Per Reading
– Electronic - $7.30 per title
– Print - $23.50 per title
26
Library Contribution to Usefulness & Value
• Purpose of use• Importance in achieving principal purposes• Ways article affected the principal purpose• How much do readers “pay” for the article?• Achievers read more from library
collections• Readers are more productive than non-
readers• Helps achieve parent organization goals
27
Return-on-Investment Defined
• Investment– Library expenditures and organization G&A
– User time in wages and overhead
– Cost of other relevant resources
• Return– Contingent valuation of the additional cost to
users if there were not library services
– Changes in user productivity, information needs satisfied, and other relevant indicators
28
Definition of Contingent Valuation
• Contingent Valuation is an economic method used to assess the benefits of non-priced goods and services (e.g., libraries or specific library services) by examining the implication of not having the product or service.
29
Library Journal Collection Return-on-Investment
• Library expenditures (amount allocated to faculty and staff use) – $1.87 million
• Faculty and staff cost to use the library collection – $1.56 million
• Total organization investment– $3.43 million
30
Library Journal Collection Return-on-Investment
• User cost to use alternative sources of article information– $11.38 million in user time– $2.1 million in user purchases
• Total cost of alternatives– $13.48 million
• Return in net benefit ($13.48 million - $3.43 million)– $10.05 million
31
Library Journal Collection Return-on-Investment
• Ratio of return-on-investment ($10.05 million divided by $3.43 million)– 2.9 to 1
PLUS– Indicators of gained needed information,
productivity, etc.
32
Total Time Saved
• Total time saved– 250,000 hours
– 114 FTEs*
• Electronic remote access savings in time– 50,000 hours
– 23 FTEs*
* based on an average of 2,200 hours worked
33
Implications of the Studies
• Technologies will continue to advance journal publishing capacities and power to inform
• Electronic journals have been extremely beneficial, but print will be relevant for some time to come
• Both readers and libraries have benefited economically from electronic journals
• Libraries will continue to be an essential participant in the journal system for the foreseeable future
• Newly proposed system models need to advance cautiously and with demonstrable successes
