Rudman's Buying Guide Question

[CBI_2]

A friend at work, who does some volunteer work at a public library, picked an old Rudman's Cigar Buying Guide for free and gave it too me. The copyright date is 1997. I have never looked at one and just started to browse through it.

2 questions:

1. Is Rudman's any good?

2. Does one 12 years old still have any informative value?

any input would be appreciated.
