A section of a book containing information about the publication and production of the book.

Through history, colophons have included a varying amount of information.

Some of the items that might appear in the colophon of an e-book are: the date of publication, the name of the publisher or producer, the names of the people involved in the production, the typefaces used in the book, the software used to produce the book, and any technical notes about the e-book file. All of these may be augmented with hyperlinks to relevant web sites.
