Thinking about selling Vinyl collection - long

I am a new member, but have been lurking here for over 5 years now. I've been long debating whether or not to get back into using my LPs again - but don't think that I'm really up for the hassle. I am going to catalogue them after we get back from a short trip to NE to see our son in graduate school. I'm not looking forward to the cataloging - if memory serves I have somewhere north of 500 or so LPs. I started collecting circa 1968 - rock, folk, jazz, celtic, fusion - etc.

I went to work after college for Audio Associates in Arlington,VA - had many good TTs - Rabco, Thorens 125w/SME - etc. - Just don't listen to LPs anymore - I doubt if any are below average in condition - some - like Hendrix Electric Ladyland import and French Stones set might have been played once.

So my question is this - what's the best way to sell them after I come up with the list of what I have?

Thanks for the advice - and for all the info and fun I've had over the years reading here!
