There are no accepted standards governing naming electronic resources in A to Z lists or electronic resource management (ERM) systems. Current practice superficially resembles cataloging standards and guidelines, but is substantially ad hoc, and reliant on local adaptation and innovation. A little more predictability is needed to make finding and using electronic resources easier. This chapter describes issues related to naming electronic resources and concludes with a draft set of principles and conventions for designating names or titles in the context of A to Z lists and ERM systems. It will also examine the unique issue of electronic resource volatility and its impact on maintenance. The focus will be on integrated or continuously updated electronic resources, such as bibliographic and full text databases, and reference works.
