John Wycliffe's Translation
The downloaded ZIP file contained 76 books comprising the 66 protocanonical books and 10 deuterocanonical books. It also included a text file providing a key to the booknames. The Biblical text files were last edited on 2002-05-24.
I prefixed the filenames for the Biblical text files with the usual book numbers, with an underscore to avoid mis-sorting filenames that already began with a numeral.
Conversion to USFM
I made a simple TextPipe filter to convert the files to rudimentary USFM, complete with ID and Header tags, plus the following remarks.
