I started out adjusting brightness levels on a histogram during or after scanning, but then realized a dark backing would make the printing invisible and save me the effort. I use black cardboard when scanning newspaper or magazine clippings in a flatbed scanner, but I figured cloth would let vacuum through. I think there are vacuum tables made for engraving and woodworking applications, or an air hockey game table might work with the blower reversed.

Camera on a stand, and make a vacuum table that sucks it flat. Use a black fabric underneath the newspaper to eliminate bleed-through from the text on the other side.
I pipe a recursive dir command output to a text file named for the disk number, and keep those text files in a folder. To find stuff, I use windows explorer to search for text inside files.
If movies came packed in an archive, I'll use the checksum from that file to make an sfv. Otherwise, I run Corz Checksum to make a checksum in each folder.
AnyDVD to a folder or iso. Then you preserve all the menus and extras.
I've never seen one that wasn't like that. 9V supplies usually have the opposite polarity, and there's 12V AC supplies too. I tag the plugs so I don't fry my hardware. And I pray that some standards organization will do something.
I purged hundreds of DVDs when I moved, movies and series I was confident I'd never rewatch, or that would be easy to find on Blu-Ray.
I still occasionally buy used DVDs, mainly foreign films and series, and mountain bike or fmx videos.
I need to do the same with my CDs. And make backups of the rare ones in case of disc rot. Vinyl likewise; but those won't be given away.
