As I'm sure you know, scanning old magazines, catalogs, etc. is a lot of work. I often refer to the Vintage Machinery website for information on old tools; it's run by Keith Rucker and he's amassed a huge amount of tool catalogs, owners manuals and so forth. Rather than using a flat bed scanner, he has a rig set up for digitizing the catalogs more efficiently that actually uses a couple digital cameras. He posted a video showing how it works a few years ago.
