If you manage to sell the LPs, by far the best suggestion here is to then purchase CDs of the same music. First, as many others have noted, digitizing hundreds of LPs will take a ridiculous amount of time, effort, and, to do it at all well, money. The kit in my pro-quailty LP to CD transcription and mastering studio runs close to $30,000 all totaled. Unless the LPs are truly rare and have never been released on CD, it’s not worth it.
Second, and this is important, it is neither legal NOR ethical to make a copy of any recording in ANY format and then dispose of the original recording. That original recording is your license to own a copy under copyright and fair use laws. It’s not likely that you’ll ever go to jail for a violation, but you WILL be ripping off the artist and others. Think about it, then buy a CD instead, and KEEP it. Ripping a CD then disposing of it is just as bad.
