Tier 2 Studies
• Over 200 good studies in last decade
• One time studies or small scale
• Variety of methods
• Together build our knowledge of user behavior
1. Researchers use many ways to get information
2. E-journals influence some behaviors
3. Differences due to workfield, workplace, and others

Interviews/surveys/ Opinion, what individuals and journals groups say they do in general and why
Critical (last) incident What individuals say they do specifically and why
Observational/ What individuals do in aExperimental controlled or natural setting

“Convenience drives usage of e-journals…and it is a relative term among scholars.”
Stanford e-Just
“What is convenient for one scholar is not necessarily convenient for others. With their own idiosyncratic approaches to both print journals and online information, and with their own configuration of professional strengths, histories, and needs, scholars patch together systems that work for them in their context.”
Stanford e-Just
