Time to weed the LPs.... (choosing stuff to dump)

I am in the process (again, every few years) of weeding the Rock LPs. Going through newer stuff to decide to sell to my fav. record store, or keep.
I do this every few years to thin out the collection gradually. Eight years ago I did a major cull removing 6,000 LPs of 12,000 to move. Over the last six years I have cut that down to 4,500 (and probably buying 500 of those during that time).For all sorts of reasons it is a good project. Get rid of cobweb covered music I have no use for, (and maybe someone else wants) Frees up a small amount of cash to waste on more Stereo junk.The main thing is the collection gets better, more just what I really like.Anyone else clear out the junk now and then?(For the question already forming... and no I will not sell them here. I have bought tons of stuff at my fav. record store, I like them, and sell all my records to them.  LOL)
