The collection includes most volumes of this publication. The earliest dated volume was published in 1969; however, there are several earlier undated volumes (they are titled with volume numbers rather than year of publication, like all following volumes), which indicate that the Labyrinth began publication in the late 1960s. The collection begins with these early volumes and continues until the present. It should be noted that there were several periods in which the Labyrinth was not published – this appears to be mainly from 1982 - 1992 and 1997 – 2003. The collection also contains some additional materials relating to the Labyrinth, such as correspondence, publicity, and advertisements. There are electronic and paper copies of some issues. Digital-only production of the magazine started in 2018.
