'536 Puzzles and Curious Problems' by Henry Ernest Dudeney, was published by Charles Scribner's Sons in New York in 1967. It is a combination of almost all the material previously published in Dudeney's 'Modern Puzzles' and 'Puzzles and Curious Problems', edited into a single volume by Martin Gardner. The material that makes use of an element of paperfolding is listed on this page.

A full copy of the work can be accessed online here.

Martin Gardner does not identify where or when these puzzles were previously published. However:

Dudeney's 'Modern Puzzles', published by C. Arthur Pearson in London in 1926 contains 'Folding Postage Stamps', 'Ribbon Pentagon', 'Paper Folding', 'Folding a Pentagon', 'Making an Octagon', 'A Crease Problem'.

Dudeney's 'Puzzles and Curious Problems', published by Thomas Nelson in London in 1931, contains 'Square and Triangle', 'Folding a Pentagon' (from a strip), 'Coin and Hole'.

Many of these may also have previously appeared in Dudeney's many magazine articles.
