Antonym for 'serial', as in 'a serial publication'

I'm looking for a word that signifies the opposite of a serial publication, where a serial publication is described like:

The first novella in a three-part series.

Or:

A quarterly publication.

The British expression "one-off" accurately describes the concept, but it seems more colloquial and dismissive, i.e., something that is meant as a draft or a prototype, than what I'm looking for. Surely this word exists.

A use case would be publishing a short-form comic or zine. Some issues would be serial: it will take 3 or 6 (or at least more than one) issues to cover a storyline. Others will be "one-off": it will only take one issue or strip or panel to cover a storyline.

Solution 1:

The domain-specific relational antonym of 'serial publication' is 'volume publication'. This works for the use case you describe, and is the traditional oppository phrase. It is inexact (not surprisingly: all antonyms are inexact, and relational antonyms particularly so), hence constructions such as "serial volume" are not only possible but in widespread use.

Solution 2:

"One-off" is, as you say, slightly British.

"Stand-alone" is frequently used in Britain and North America.

"One-shot" is also used for comics.

Solution 3:

A publication that is not serial is a one-time publication. This usage beats out stand-alone even in Ngram’s American corpus. It is official terminology for Canada Post, though lumped together for postal purposes with annual publication. The term is also sometimes used in a slightly different sense, though, associated with the granting or selling of publication rights by an author to a publisher.

Solution 4:

For a one time publication of either a scholarly or casual work you can use the term Monograph.

Solution 5:

For a magazine, I would use Special edition

Example: We are currently working on a special edition of The Lancet to promote the latest thinking on this critical issue.
