While the term "Codex" was not yet used, a number of books were comparable. Like the more modern editions, they included units and rules that were compiled from White Dwarf.
Boxed set volumes
The 2nd Edition was substantially more colourful and the new Codex books reflected this fact. More detailed information, such as background and organisation, was included, adding more depth and details to the Warhammer 40,000 universe.
Campaigns and Supplements
The 3rd Edition Codexes were much smaller and less detailed than the second. This is because several new races were invented and five or six codexes a year could be produced.
Some Codexes were amended or rewritten during 3rd Edition.
Campaign and Settings
Within the 3rd Edition a new type of Codexes were published. Rather than providing information on a specific force, these included new rules and background for environments or planetary campaigns.
With the introduction of the 4th Edition of Warhammer 40,000, the Codices have been updated and re-released. The fronts of the Codices are back in a consistent style, as it was in the 2nd Edition.

Campaigns and Expansion
As in 3rd Edition, the 4th Edition of the rules also introduced Expansions, Codexes that don't deal with a single force, but rather expand the rules for select settings and situations.
