Sets in Order archive
The complete collection of Sets in Order (which changed its name to Square Dancing in 1968) is available online through the University of Denver. The issues were scanned by New Jersey dance caller Gardner Patton. You can read more in this interview of Gardner Patton conducted by Bob Brundage in 2011. A handy and attractive guide to the many issues is here.
The complete run of the magazine was 444 issues. The host is the University of Denver's Penrose Library, home of the Bob Osgood collection.
A librarian at UDenver confirmed, "There is no indexing of these issues, but there is a full text search capability." See the suggestions on how to search the digital Sets in Order within individual issues and in the collection as a whole.
