I have Alison Baltier for Access Development. Interestingly, her information about ODBC is almost dead-wrong as Pat Hartman has blasted the myths such as needing unbound forms and doing everything manually (which is what Alison claims you need to do). After that, this is probably most useful reference book and I always use it when I need a nudge to my memory.
As for the whitepaper, I'm not sure where else to get more introductory as I felt that was *the* introduction. Maybe if you googled?
Now to fix my sarcasm detector...
