Carter's article discusses the monograph versus serial question for online resources, specifically looking at cases where a library owns both print and online versions of the resource. She outlines the pros and cons of monographic and serial treatment, presents a brief survey of the cataloging practices of a sample of ARL libraries (for a single title), and provides sample OPAC screenshots to illustrate the information users are given in a results list for various cataloging practices. Cataloging decisions are complicated by the publisher's decision on how to present the titles, the availability of MARC record sets, and how the title is treated in the library's link resolver's knowledgebase.
