- Abstract
- Studies the effects of e-journals on the scholarly communities they are serving. Considers to what extent scholars and researchers are aware of, influenced by, using, or building their own work on research published in e-journals. Draws a sample of scholarly, peer-reviewed e-journals and conducts several analyzes thorugh citation analysis. The data show that the impact of journals on scholarly communication has been minimal
