Math Reviews JSTOR Use
22
Usage by Discipline - 2001
23
Relationship Between JSTOR Use and Citations by
Discipline
24
Interpretation

• Overall citations do not predict JSTOR use well
  at all. In other words, highly cited articles
  are not more likely to be highly used.
• It also means usage is not dominated by users
  trying to build a citation list, or by people
  coming to articles because they saw them cited in
  another article
• There are variations by discipline. Citations
  and articles printed from JSTOR are more related
  in Economics and History than in Mathematics

25
Relationship Between JSTOR Use and Age of the
Article, by Discipline
26
Interpretations

• Overall, age of the article does not predict
  JSTOR use
• More recent articles are not more likely to be
  highly used than older articles
• There are variations by discipline. History
  journals show the highest correlation between the
  age of the article and use. People using history
  journals seem to be using more recent articles.
