The Programmer's Guide To LDOS/TRSDOS Version 6
The Programmer’s Guide is my favorite TRS-80 programming book, and in my opinion, the most useful. The chapters include:
- an overview of the operating system
- device input/output, with information about filters and drivers
- disk drive input/output, with information about writing a disk driver
- DOS directory structure
- disk file access and control
- interfacing with supervisory calls (SVCs), including detailed information about parameters
- other useful miscellaneous tables and topics

Programming the Z80
Even though Programming the Z80 was not written for the TRS-80, it was one of the more popular TRS-80 programming books. I suspect that this book and TRS-80 Assembly Language Programming by William Barden introduced more TRS-80 programmers to assembly language than any others.
