Need information on TRSDOS 1.3 internals

Does anyone have any documentation on the data structures of TRSDOS 1.3? Specifically, I'd like to know the catalog structure, as well as the scheme for storing files across multiple sectors. I'm trying to pull some old word processor and perhaps spreadsheet files off some TRSDOS disks using a PC. I already found a utility called READDISK that reads TRS-80 disks on a PC and it worked great. Now I need to extract the files from the image. Is this data published in any of the TRS-80 DOS manuals?
