The last few pages of the book

    The Definitive Guides to the X Window System
    Volume Two - Xlib Reference Manual (for Version 11)
    O'Reilly & Associates, Inc.

contain extremely useful quick reference "At-a-glance" tables about
window attributes and GC's.

A quick reference card that we have found helpful here is one that
explains how the X resource database is loaded. I am posting it in the
hope that others may find it handy.

--- Start ---

For clients using the R3 X Toolkit, the resource database is loaded and
merged in the following order.

    1. /usr/lib/X11/app-defaults/<class>

    2. if XAPPLRESDIR set
               $XAPPLRESDIR/<class>
       else
               <home>/<class>

    3. if server's RESOURCE_MANAGER property set (by xrdb)
               contents of RESOURCE_MANAGER
       else
               <home>/.Xdefaults

    4. if XENVIRONMENT set
               $XENVIRONMENT
       else
               <home>/.Xdefaults-<host>

    5. command line (e.g. -geometry, -xrm)

--- End ---

The above information is the sort of thing you want to give to beginners
who are baffled when their .Xdefaults files don't seem to work since
they are (also) using xrdb without knowing about it.

An at-a-glance card that I would really like to have is one that
indicates which GC values are used by each drawing function. What I have
in mind is a 2-dimensional table with the GC members along the top and
the drawing functions down the left side. The entries could be * to mean
that it is used, ? to mean "depending on function", and space for not
used. Has anyone got something like that?
