Research for maps?

Yes, we are still in the "low" tech era when it comes to maps and records researching.
What keeps us from getting into the "high" tech era is of course money and cooperation.

Here's a couple of questions that will help us target your needs.

We have a database for recorded maps and Corner Records.
What file format or what program would be more beneficial to you?  i.e. MS Access, FileMaker Pro

How do you typically search by? street? APN? County Grid number?

Thanks in advance for your feedback.
