Digital reference service: trends in academic health science libraries.

Two years after the initial 2002 study, a greater number of academic health science libraries are offering digital reference chat services, and this number appears poised to grow in the coming years. This 2004 follow-up study found that 36 (27%) of the academic health science libraries examined provide digital chat reference services; this was an approximately 6% increase over the 25 libraries (21%) located in 2002. Trends in digital reference services in academic health science libraries were derived from the exploration of academic health science library Web sites and from digital correspondence with academic health science library personnel using e-mail and chat. This article presents an overview of the current state of digital reference service in academic health science libraries.
