I've used Cornell on several occassions and have a number of repro. catalogues from there. I find them very useful for "research" purposes - especially when I run out of options on some aspect of a firearm. In particular, I was able to establish that a Bonehill Matthew Eclipse was in fact a separate Model & not "Grade" for some
other model produced by Bonehill. It took awhile but I got there through Cornell Pub. Fwiw --- John
