Monographs and multi-parts (e.g., an encyclopedia). Finite resources are issued once, or, if issued over time, they still have a predetermined conclusion (such as The New Encyclopedia of Southern Culture).
Continuing resources are issued over time with no predetermined conclusion. Serials (e.g., periodicals and continuations) are issued in a succession of discrete parts. Integrating resources (e.g., loose-leaf publications, databases, and websites) are defined by updates that are incorporated into the whole of the resource, instead of being issued as discrete parts. (Integrating resources can also be finite or continuing, but don't worry about that because it doesn't affect how they are cataloged.) Each instance of an integrating resource, whether the first publication or a subsequent update, is referred to as an "iteration". Fun fact: Integrating resources that are no longer being updated should still be cataloged as integrating resources.
Notes on Loose-leaf Publications:
We haven't gotten any new ones in a while and it's unlikely that it will be a frequent occurrence, but we do still receive some updates to existing loose-leaf pubs. They do not require cataloging. Just receive them and send them to Melvalee or RIS as appropriatethe designated department on the serial control or order record.
Notes on Electronic Resources Mode of Issuance:
Keep in mind that, from a cataloging perspective, electronic resources can be monographs, multi-parts, serials, or integrating resources. You have to figure out how they are issued in order to make the distinction. If the electronic resource will be updated and the updates are discrete (like the online version of the Journal of Veterinary Behavior), it is cataloged as a serial. If the updates are not discrete (i.e. changes are integrated into the resource and earlier iterations are not readily available, like the NCSU website or The Artstor Digital Library), it is cataloged as an integrating resource.
