  1. Electronic Journal Use: A Glimpse Into the Future With Data From the Past and Present Carol Tenopir University of Tennessee ctenopir@utk.edu Donald W. King University of Pittsburgh dwking@pitt.edu C. Tenopir

  2. Introduction Total number of periodicals ~250,000 Number of refereed scholarly periodicals ~15,000 Number of online refereed scholarly periodicals ~12,000 C. Tenopir

  3. Not All “E-Journals” are the Same • Full Journal Titles • Database of Journal Articles • Separates in E-print Servers • Authors’ Website C. Tenopir

  4. Other Differences • New design or replica of print • Added data and features • Browsing or searching • Backfiles C. Tenopir

  5. Not All Readers Are the Same • Variations by workfield • Variations by workplace • Variations by purpose C. Tenopir

  6. Groups Compared • Astronomers in 2001/2002 (heavy users of e-journals) • Other scientists with recent but relatively infrequent use of e-journals (2000-2002) • Scientists before extensive availability of e-journals (pre 1995) C. Tenopir

  7. Data From: • 15,000+ scientists and social sciences • Many workfields • University and non-university settings • 1000+ members of AAS C. Tenopir

  8. Time Spent and Number of Articles Read C. Tenopir

  9. Stages in Electronic Journal Reading Early (Pre-Web) (2000 ) Evolving Print emphasis Mix of print and electronic ~35% total readings from electronic (2001 ) Advanced Electronic emphasis Mix of print and electronic ~80% total readings from electronic C. Tenopir

  10. Source of Articles Read By Electronic Journals Experience Early Evolving Advanced Personal subscription 46% 37% 15.2% Library Subscription 41% 48% 49% Separates 13% 15% 35.8% C. Tenopir

  11. Sources of Readings % and amount of readings from separate copies use of personal subscriptions Scientists appear to be reading from more journals—at least one article per year from approximately 23 journals, up from 13 in the late 1970s and 18 in the mid-1990s. C. Tenopir

  12. How Scientists Learned About Articles Early Evolving Advanced Browsing 58% 45% 21% Online Search 9% 14% 39% Colleagues 16% 22% 21% Citations 6% 13% 16% C. Tenopir

  13. How Scientists Learned About Articles Browsing Complete Journals Online Searching by Topic Electronic versions provide additional functions (searching, citation linking) which replace some browsing C. Tenopir

  14. Browsing Searching • Core titles • Current issues • Background • Current awareness • New topics • Old articles • Support primary research • Support writing C. Tenopir

  15. Age of Reading from Digital Media 1 years 2-5 years 6-15 years >15 years C. Tenopir

  16. CONCLUSIONS • More reading in all workfields in not much more time • Users prefer convenience and familiarity • Browsing journal titles for core sources (print or electronic) • Searching separates for additional sources C. Tenopir

  17. CONCLUSIONS • Complete journals and databases of separates will coexist • Differences in workfields (Build it right and they will come) C. Tenopir
