Partwork
A partwork is a publication released as a series of planned magazine-like issues over a fixed period, weekly, fortnightly or monthly, so that the finished set forms a reference work or, very often, a complete model built part by part.
Definition
Partwork series run for a set length and have a finite life. They cover particular interests, such as sport, hobbies or children's stories. Many include items mounted with each issue that build into a complete set over time: paints that become an art set, replica bones that become a skeleton, or parts that become a model car, robot or figure. Collectable models are especially popular in Europe, and the same series can be sold worldwide in different languages and variations. A common inducement is a heavy discount on the first one or two issues.
Origin
Serial publication is old. Before printing, the pecia system in European university cities divided books into sections that could be rented and copied, and serialised publication came into use soon after printing arrived. Between 1728 and 1732, an English translation of Rapin's History of England was issued in monthly parts by a London printer; advertising for part-works survives from London in 1810; and many of Charles Dickens's novels first appeared as partworks in the nineteenth century. In the mid-twentieth century, encyclopaedias were issued as partworks, and completed partworks have sometimes been bound into reference works. In the United Kingdom, partworks were long launched with heavy television advertising each January, and in 2003 they were the fourth best-selling magazine sector there.
In the house, Japanese partworks reach us from DeAgostini, Hachette and Kodansha, whose series build cars, aircraft, robots and dioramas. In our handling, the completed builds are the pieces collectors look for, because finishing a series takes months or years and a working completed model is rarer than the sum of its issues.
Two kinds of piece reach us. The first is the finished model, built by its owner over the life of the series, sometimes with upgrades or repairs, which we describe. The second is the run of issues, sealed or opened, with magazines and parts still separate, which suits a buyer who wants to build. Both are honest objects; they simply ask different questions about completeness and condition. Where a model was finished by a skilled hand, we say so, and where it was finished in a hurry, we say that too.

How to read a finished build
- Completeness. Count the issues and parts against the series total; magazines, binders and bonus items all count.
- Function. Lights, sound, motors and electronics should be tested and described; we say what works and what does not.
- Build quality. In our handling, glue marks, stripped screws and misaligned panels show in close photographs, so we take them.
- Display. A case, base or diorama is often part of the series and part of the value.
Where it appears in the collection
A Kodansha communication robot Atom assembled from the weekly Astro Boy partwork joins a DeAgostini Godzilla 1954 remote-control model with its full diorama and a Hachette Zero Type 52 gimmick model, completed. Astro Boy is read in our Astro Boy collecting guide and Godzilla in our guide to collecting Godzilla; finished builds sit on our scale models shelf.
