Two such Yearbooks were produced. 1997's, which appeared on cue in December of that year, is notable for being the first instalment of Monomyth to contain work by contributors other than its original four founding writers. 1998's, meanwhile, did not surface until December 1999, a whole year late, owing to the problems of schedule slippage that plagued the magazine at this time — and would lead to it going on an extended break from publication, the Great Monomyth Hiatus, after just one further issue.
By the eventual resumption of output, the two Yearbooks had been reclassified as issues in their own right, which saw the renumbering of the series henceforth to create an 'absolute' count that would include them. The first Yearbook became retrospectively classed as 'Issue 11' (a.k.a. Volume 1.11) and so is listed on this wiki as Monomyth 11, whilst the second became 'Issue 22' (Volume 2.11) and is listed here as Monomyth 22. Subsequently, however, the tradition of producing an annual Yearbook has not been revived.
