SPT?

Anyone here familiar with the SPT? (Society of Photo-Technologists International)

I am not a camera shop, or a pro repair tech. I have been considering joining as an associate to gain access to the library. I'm wondering how large the library is, when it comes to service manuals. You can't see what they have until you join. But I am not familiar enough with them to know if I want to join.

I don't envision going pro, I just like to tinker with dead technology.

Thanks!

I was a member years ago, The manuals are mostly tips on less common problems with solutions from members throughout the US.
I recall they had a few issues with more complete disassembly procedures but not especially well illustrated(photos, not the best quality.).
In a world with little or no information like this, it is better than nothing.
