One good text, although slightly dated, is _X.25 Explained:  
Protocols for Packet Switching Networks_ by R.J. Deasington
(Ellis Harwood Ltd., a division of John Wiley & Sons).

There are quite a number of standards associated with "X.25,"
in the CCITT and ISO world.  X.25 itself references some physical
layers (e.g., X.21 and X.21 _bis_), and covers the frame and
packet levels.  There are ISO standards paralleling these:
ISO 7776 for the frame layer and ISO 8208 for packet.  ISO 8878
deals with providing the OSI Connection-Oriented Network Service
over X.25.

CCITT also has a number of related standards, such as X.121
for the addressing plan and X.87 hypothetical reference 
connections.  The X.135-X.139 series deal with performance.

These are from memory; there are a number more including the
X.25 interface to ISDN.
