"The Keep on the Borderlands" went out of print in the mid 1980s. However, the module was partially reprinted in the "supermodule" compilation B1–9 In Search of Adventure (1985), which included the Caves of Chaos but not the keep or surrounding wilderness. A reprinting of the original adventure was made available in the "Dungeons & Dragons Silver Anniversary Collector's Edition" boxed set in 1999 to celebrate the 25th anniversary of the "Dungeons & Dragons" game, with slight modifications to make it distinguishable from the original (for collecting purposes).
