Search archive.org for your favorite subjects. They have millions of books, pamphlets, magazines, audio files, and videos. People have even uploaded newer stuff that may not really be out of copyright.
You can even download an ISO file of Windows XP so you can put it on a computer and go back to the older days of software that just plain worked. They have tons of older computer software free for the download.
I have spent many hours downloading from archive.org.
