John Clews can, no doubt, provide some sources for general background
on EBCDIC in the context of all the other character sets.

But the "horse's mouth", so to speak is:

Character Data Representation Architecture Reference and Registry
(CDRA), Document SC09-2190-00, Second Edition, December 1995. IBM.

This is a publicly available document which can be ordered through
any IBM representative or IBM branch office. It contains a CDROM
with all the code page specifications, together with software to
access them and a CDRA interface definition (e.g. for converting
between IBM code pages directly). The printed part of the document
lays out both the EBCDIC and PC encoding schemes in excruciating
