ArchiveGrid is currently available without a license. It's a very cool tool. Before its doors are slammed close, I wanted to take the opportunity to plan out an archival Haj of sorts:
The papers of Eugene S. Ferguson, at the Hagley Museum and Library. RLG Union Catalog Record ID: DEHX155748-A.
[nb. I'm the proud owner of one of Ferguson's books, notably his commentary on Ramelli. I actually own the presentation copy of his co-author, Martha Teach Gnudi. She seems to be unrepresented in the archives. The Edward Eyre Hunt Papers, 1902-1953 do, however, contain some correspondence between Hunt and "Mrs. Dante Gnudi" (Box 3 of Correspondence). The papers are preserved at the Hoover Insitution at Standford University. Hunt was a big wheel in the effort to restore Europe following the war and wrote about social welfare in the context of labour efficiency. The connection is interesting if only because of Hunt's connection with Hoover, the translator of Agricola's De Re Metallica.]
Additional holdings are available at the Smithsonian, as noted in the previous post.
Harold Reeve Sleeper Papers, 1911-1960, at the Cornell University Library. NIC #2135. RLG Union Catalog Record ID: NYCV85-A346.
I still have an abiding interest in Architectural Graphic Standards. Cornell also holds recordings of the Libe Cafe Events, including lectures by John Cleese, Oliver Sacks, and Jane Goodall. I wonder if they presented together. That would have been very trippy.
The Honeyman Ramelli.
Yale's Elizabethan Club currently owns the Honeyman Ramelli, a highly annotated copy of the work on machines. It was previously owned by Thoman Arundell and contains annotations written in English by two different hands. Steve Parks, curator of the collection, provided me with these comments (via the very helpful Kathryn James):
"I had a good look at the Ramelli yesterday afternoon. There are notes on the front endpaper and fly, notes and underscoring in the text, and quite a few pages bound in at the end. Some pages have been excised. The writing often goes to the margins, which are often somewhat frayed. The notes in the text are faded brown and often blurry, while the added notes are dark and more legible. These pages are bound pretty tightly, but I imagine that quite a bit could be read in microfilm, ...but not in xerox which would harm the volume. The notes are in Engllish. In short, I really think that the reader needs to examine the book to fully understand it. Thanks for responding to him."
