scan aircraft log to CD

I'm sure some of you here have scanned your logs into a machine readable format.
Please let me take advantage of what you've learned.

Do you store the scanned pages as .jpg, or .pdf, or something else?

Each page a separate file?

Any special software?

Did you build an index? If so, how?

Will all the pages of a typical spamcan log fit on a single CD?

Any other hints?

Thanks.
