Where to sell 100s of music books

[dreamygirl25]

Hi there, I have over 100 music books. much more than 100. Mainly for piano but perhaps 5% are violin. I just don't use them, is there a place that buys them? What can I do?

We buy books? Or ebay.

Ah I didn't think of ebay. So obvious. I tried we buy books and they have no bar code
