Transactions of the Doppelganger Society

Transactions of the Doppelganger Society was a literary supernatural and horror publication edited by David Cowperthwaite.

Published in 1990, this was a one-off booklet limited to 100 hundred copies.

The cover, and illustrations, were by Colin P. Langeveld.

Contributors of fiction and poetry were, in order of appearance, Colin P. Langeveld, Ramsey Campbell, Daphne de Rose, Mark Valentine, Malcolm Furnass, John Howard as 'Sir Oiver Nutherwun', Keith Jones (Nerve Gardens), Joel Lane, Doppleganger Dan, David Cowperthwaite, William A. McCabe, Barry Duggan (Nerve Gardens), and John Whitbourn.

Rosemary Pardoe wrote of the collection, that it was, "highly recommended and well worth the wait...Aside from the excellent Campbell and Whitbourn stories, the best of the rest are those which give some insight into, or are at least firmly in the spirit of, the Doppelganger Society."
