Partwork

A partwork is a magazine format, designed to form a collection based around a particular subject. Usually heavily geared around a subscription model, partworks are typically released on a weekly, fortnightly, or monthly basis, and often take over a hundred issues to complete the collection. In the UK, the partwork format is one of the most popular magazine formats.

Several types of partwork are common:
 * A reference collection, with each issue containing the magazine alone.
 * A model-building collection, with each issue containing parts to contribute to the final complete model.
 * A DVD collection, with each issue including a DVD of the subject series.
 * A collectable model series, with each issue including a complete model.
