There is a studio studio here in Massachusetts that digitizes cassette tape, video, etc. I work with several different organizations and their archival collections and this studio was referred to me by one of the historical societies that they had done cassette digitization for. I have just been in touch with them for a quote for a grant application for an oral history collection that’s on cassette, some reel to reel and some video cassettes. I asked if they work with organizations out of the area and they do indeed. The name of the studio is: Tom Tracy Studios, Tom Tracy is the owner, phone number is 508-776-8968, email is: firstname.lastname@example.org. Tom is really great to work with and quite knowledgeable and accommodating. Hope this helps!
