Specifications for leather

From: Richard Okanishi <*ricok*> Date: Tuesday, September 8, 1998 · ricok

We need to know if there exist and which would be the world's
specifications for leathers and parchments to use in restoration and
bookbinding, such as thickness, solidity, permeability, etc..
Thanks,
