This document discusses factors to consider when selecting serials for a library collection. Serial publications like journals, magazines, and newspapers require long-term commitments as they are intended to continue indefinitely. This means that serial costs become a fixed part of the budget each year and occupy more storage space over time. When deciding whether to subscribe to a serial, librarians must weigh the ongoing costs of subscriptions, processing, packaging, and potential photocopying against how patrons will access the information and whether to purchase back issues.
