When I took a bibliography seminar in grad school, the Wise Forgeries were one of my favorite topics. The discovery of the forgeries by Carter and Pollard and the discovery of the thefts by Foxon are true landmarks in bibliography. It’s worth hunting up a copy of Carter and Pollard’s “An Enquiry into the Nature of Certain Nineteenth Century Pamphlets” and Carter’s Thomas J. Wise and His Forgeries, both of which are surprisingly thrilling reading.
