Marvel Ultimate Collection, Complete Epic and Epic Collection lines

Marvel Ultimate Collections/Complete Collections, Complete Epics and Epic Collections are large full-color trade paperback collections of previously published Marvel comics, typically containing 300–500 pages. The Ultimate Collection/Complete Collection lines collect entire runs of one title, or related titles by one creator. The Complete Epic line collects large crossovers spanning several titles. The Epic Collection line is a numbered collection of sequential issues of one title, sometimes including crossovers from related titles, starting from the beginning of a character. This collection is not released sequentially, as the priority is to fill in periods not covered by previous collections.
