  1. Using E-Journals To Promote Information Worldwide Carol Tenopir University of Tennessee ctenopir@utk.edu C.Tenopir

  2. How Electronic Publishing is Changing Access to Information • Scientists read more in not much more time • Scientists read from a greater variety of sources • Readers use many ways to locate information • More readers, more readings, more citations C.Tenopir

  3. 1. Scientists read more in not much more time C.Tenopir

  4. Average Time Spent and Number of Articles Read Per Year Per Scientist C.Tenopir

  5. Scholarly Article Reading C.Tenopir

  6. Differences Among Work Places and Work Fields • University faculty read more than non-faculty • Medical faculty and practitioners read more articles than most (but spend less time per article) • Engineers read fewer articles (but spend more time) C.Tenopir

  7. 2. Scientists read from a greater variety of sources C.Tenopir

  8. 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 26 journals, up from 13 in the late 1970s and 23 in 2000. C.Tenopir

  9. Reading from Print and Digital C.Tenopir

  10. 3. Readers use many ways to locate information C.Tenopir

  11. 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

  12. 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

  13. 4. More readers, more readings, more citations C.Tenopir

  14. Los Alamos/Cornell arXiv.org • Connectionsreached 200,000 per day in May 2001 • 35,000 new papers in 2001 • Each article gets an average of 300 downloads per year C.Tenopir

  15. PubMed searches per month Searches per month (Millions) Year searches were conducted C.Tenopir

  16. Steve Lawrence, “Online or Invisible?” Nature, v.411 n.6837: p.521, 2001. www.neci.nec.com/~lawrence/papers/online-nature01/ C.Tenopir

  17. Highly cited and recent articles are more likely to be freely available on the web C.Tenopir www.neci.nec.com/~lawrence/papers/online-nature01/

  18. The percentage increase for the average number of citations to online vs. offline articles C.Tenopir www.neci.nec.com/~lawrence/papers/online-nature01/

  19. Summary of What Has Changed • Scientists read more • Scientists read from a greater variety of sources • Freely available online articles are read and cited more C.Tenopir

  20. Some Things Do Not Change: • Scientists value high quality information • Scientists must read more in not much more time • Scientists value sources that allow them to make the best use of their time C.Tenopir
