Editing Edition (book) (section)

=== Co-edition <!-- Section linked from Horus Heresy (novels) --> ===
The basic definition of a ''co-edition'' is when two publishing houses publish the same edition of a book (or equivalent versions of an edition, for example, translated versions), simultaneously or near-simultaneously, usually in different countries. English and American editions may [[American and British English spelling differences|differ in spelling]], and they [[list of works with different titles in the United Kingdom and United States|sometimes have different titles]]. Some examples:
* An English-language edition, from the same plates, films, or files, may be published in different anglophone countries by different publishing companies. For example, Arms & Armour Press in the UK and Stackpole Books in the U.S. published co-editions of various monographs on military matters.<ref>{{Harvnb|Leventhal|2006}}.</ref> 
* A French-language novel published in France this year by a French publisher could become an English-language translation published in the U.S. next year by a U.S. publisher.

The motivation for co-editions has often been to use the existing distribution systems of the different publishers in each country rather than establishing new distribution systems.

Advancing [[Information technology|IT]] and the globalization of publishing have been blurring the lines of what ''co-edition'' means. For example, anything published online is effectively published worldwide. Also, large multinational publishers now have existing distribution systems for their hardcopy books in many countries, so they don't need to partner with other companies. They may issue a book under a different imprint for each country, but the imprints are parts of the same parent corporation. The actual manufacturing of the books may be done in China regardless of where the copies will be sold.
