Looking for Recommended Reading

[pawlowski6132]

I'm interested in Gibson guitars from 1900 to 1910.

Are there any comprehensive definitive sources available?

I already have Spans guide and other online resources are spotty at best.

I'm hoping to avoid large volumes covering a broader topic wherein these specific guitars are less than 1% of the book content of possible. They tend to treat this period lightly and can't go into depth.

Thanks in advance.
