Dear list members,
I've just come across a collection of 168 Sharada manuscripts of Kashmir Shaivite texts https://archive.org/search?query=creator%3A%22Mcintosh+Skipper+Roth%22

Does anyone know anything about this collection?  Who posted it, an individual named McIntosh Skipper Roth, or is this three individuals.
Thanks, 
Harry Spier
