This article aims to find out and analyze the development of reference services in college libraries and
increase professional understanding of information about developing reference services. This research
used the library research method, where data is collected, processed, and analyzed using the library
services websites available in tertiary institutions and books and literature related to the topic of
discussion. The results showed that the provision and utilization of reference services of several
university libraries had experienced many shifts. The change in service concept from conventional to
virtual service, shows that librarians utilize technology media in providing reference services. The
main change that can be seen from the application of technology in reference services is the increased
availability and accessibility of electronic resources in reference services, especially in college libraries.
This condition can be seen from the results of a study of several university library web pages in
Indonesia.
