Within the last few years, electronic resources have
become a prominent, if not the most dominant, means of
discovery and research for users of all types of libraries.
Although much of the electronic content for which libraries
provide access is in the form of electronic journals, there is
a growing proliferation of databases and indexes that lead
users directly to full-text content, both serial and monographic.
The variety of electronic resources and means of accessing
them has led to discussions regarding cataloging and online
resource management. Workflow and concomitant staffing
issues have also become prevalent in the literature as libraries
adjust to the realities of acquiring and processing these non-
print materials. Electronic resources have challenged the
principles and practices of cataloging over the last several
years. The complex nature of cataloging and the changes
necessitated by electronic resources have led to the need for
guides to explain the rules in what may be perceived as more
“practical” terms.
