Suggestions for Organizing Aircraft Documents?

Pending completion of the pre-buy/annual inspections I'm about to
become 1/2 owner of a Cherokee. My partner is the current owner of the
aircraft and she also owns an aerobatic plane. My guess is that I will
end up taking over the record keeping etc. on the plane. Mainly
because I want to.

I got the chance yesterday to look over, briefly, the aircraft records.
Now this is my first purchase and I'm a student pilot so I had no idea
how they should be organized. However my impression is that they
really weren't. And I certainly wouldn't want to sit down with the DPE
and "prove" to him the aircraft was airworthy.

As part of the inspections the IA / A&P supervisor has agreed to go
over the docs with me. But I was hoping for some suggestions on how
best to organize and maintain these records. I'm sure I'll find out if
it is all there, but I'm a bit anal about keeping things organized.

Any good record organizing products out there that I should consider
buying?

Recommended books?

All are welcome.
