Patent-of-the-Day .pdfs and Picture-of-the-Day photos can be saved by anyone as a personal library. Heed Robert's request to not re-post Pictures-of-the-Day, they are to be viewed on AW only via the random daily rotation.
I've saved them for years. Patents are saved in folders named by manufacturer (Misc for those not attributed to a specific manufacturer). I append the "Filed" date in format of yyyy-mm-dd and a brief description to the file names so they sort in date order by file name. Pat 4,174,622 for example is file name 1978-07-27 Direct-Drive Tub Suspension 4174622.pdf.
