[ARSCLIST] Question about grooves and styli

[Bria Lynn Parker <blparker@xxxxxxxxx>]

Hi all,

I am quite the amateur in the audio world (still a student!), and as  
part of a preservation internship I am assessing a collection of 10",  
78 rpm, lacquered discs (w/ aluminum base) from the 1950s. As a part  
of my learning experience I am trying to identify groove types for  
these discs, and for others, and was hoping I could get some advice  
from the experts out there on the ARSCList on how to identify groove  
types. There seem to be a few websites out there, but I am loathe to  
trust them without some more information.

Also, if any of you can point me to a trustworthy resource on  
selecting styli for the various groove types and discs, I would  
greatly appreciate it.

Thank you,
