"Inside Atari Dos" is compiled by Bill Wilkinson.  The publisher is Compute!
Books, a division of Small System Services, Inc.  The ISBN number is:
0-942386-02-7.  It deals with how DOS.SYS works, its most important routines,
and how a disk is set up.  Note that there is an error in how a sector in a
file is set up, if I remember correctly, the byte which says how many data 
bytes in a sector is 127, not 125 (bytes go from 0-127 for a single density
disk).  The book also contains the source code for DOS.SYS and DUP.SYS.
