If you want to do it efficiently, a camera isn’t the best way to go because it requires manually turning the pages. It’s cheap but labor intensive.

Scanners are so cheap now that any decent one can be had for $120-200. But if you want to take this a step further, buy a second hand printer-scanner combo. Doesn’t matter if the printer is broken because you don’t need it. Just make sure it has batch scanning abilities.

Get a cheap paper slicer /guillotine and rip the magazines into uniform stacks. Load into the tray and start scanning.

The thing you’ll likely run into is the tray not having the capacity required to scan all sheets in one go. Therefore, you’ll need to scan part files and combine them on the back end. You likely need paid software for this, but there is probably open source options. Either way, fly the black flag lol…

I did this after purchasing $800 worth of mechanical PE prep materials and wanted the flexibility and future proofing of my purchase. This proved a worth while endeavor after a flood took my hard copies. YMMV
