To identify the proportion of libraries conducting digital reference servic
e and to examine the characteristics of: those services, we conducted a sur
vey of 150 academic library Web sites. Approximately 45 percent of the surv
eyed libraries offered digital reference services, with higher proportions
among larger and more comprehensive institutions. We also examined: direct
links from library homepages, ways in which users submit questions, FAQ doc
uments, policies, technological barriers, and the role of institutional con
trol.
