All of the reprints in the /ubu series from books that were not already digitized (any title published before 1992 will be one of those) have been painstakingly reset, either after having been scanned and OCR’d, or being retyped into the computer. More recent titles are based on the files used to produce the original book, either from Word files or, in that rarest of instances, Quark files.
