The IP Mall, an online resource center for intellectual property information provided by the Pierce Law Center in Concord, NH, has digitized a fascinating collection of Patent Office Research and Development Reports from the 1950s and 1960s. The reports describe the Patent Office’s early attempts at “mechanizing” or automating patent searching using coding schemes and early “punched card” computers.

Patent Librarian's Notebook 
You know the funny thing about this? Plenty of patent searchers will still swear that this is the way to do a search: Grab a class or subclass, and go through every one. Sure, that technique has its place, but given the powerful keyword searching that is available, and even more sophisticated techniques like Latent Semantic Analysis to help find the most relevant documents, its amazing to me how many searchers seem to be Luddites.Sincerely,James< HREF="http://www.freepatentsonline.com" REL="nofollow">Free Patents Online<>
