The magazine was published for one year, from January 1998 to January 1999, spawning 52 issues. Subscribers were given special binders to keep all 52 issues (13 issues per binder). A special "Timeline sticker album" was included with each subscription, and each issue would come with special stickers for readers to add to their timeline based on the different topics. An index for the entire collection was also included along with the final issue to complete the encylopedia set.
