This issue is 60 pages long, not including the cover pages. It's published in the same format introduced with issue 258.
The contents of Slingshot 266 are as follows. For games articles, I've indicated the relevant rule set where it's not immediately obvious from the title; with historical articles I've tried to indicate period if a similar issue applies.
