The Masterpieces subsection is visibly unfinished - it omits Leather Goddesses entirely and has a placeholder in the prose - so prefer disc evidence where the two disagree.

• Redump: http://redump.org/. This repo’s pressings of Masterpieces (disc 64685) and The Zork Anthology (disc 82144) hash-match their entries; Redump’s Infocom coverage is otherwise thin - the Lost Treasures volume 1 CDs appear absent entirely.
