A general number in the print annual, edited by Eckhard Gerdes. General issues carry no single theme and no tribute subject. They are open-submission gatherings of the most ambitious prose the editor found that cycle, which is why the scope tends to run panoramic, style to style and influence to influence.
The journal has appeared on a roughly bi-annual schedule since 1986, with single-author Festschrift volumes for Federman, Barth, and Jaffe interleaved among the general numbers. The numbered editions are where the press takes the measure of the form between those tributes.
