Title: Electronic Journal Use: A Glimpse Into the Future With Data From the Past and Present


1
Electronic Journal Use A Glimpse Into the Future
With Data From the Past and Present
  • Carol Tenopir
  • University of Tennessee
  • ctenopir_at_utk.edu
  • Donald W. King
  • University of Pittsburgh
  • dwking_at_pitt.edu

2
Introduction
Total number of periodicals 250,000
Number of refereed scholarly periodicals
15,000
  • Number of online refereed scholarly
    periodicals 12,000

3
Not All E-Journals are the Same
  • Full Journal Titles
  • Database of Journal Articles
  • Separates in E-print Servers
  • Authors Website

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

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

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)

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

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

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

How Scientists Learned About Articles
Browsing Complete Journals
Online Searching by Topic
Electronic versions provide additional
functions (searching, citation linking) which
replace some browsing
14
Browsing
Searching
  • New topics
  • Old articles
  • Support primary research
  • Support writing
  • Core titles
  • Current issues
  • Background
  • Current awareness

15
Age of Reading from Digital Media
1 years
2-5 years
6-15 years
gt15 years

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

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