It's an almost bottomless pit, just like collecting the damn records. I believe just as there will always be something missing from the collection, there will likewise be records missing from youtube, for various reasons. I think youtube is great and post, very infrequently, on there often finding that a lot of these records haven't been posted previously. It would be fair to assume that some of the rarer or more obscure records are generally less likely to be posted but more surisingly to me is that plenty of the cheap, freely available discs don't find their way onto youtube either. Perhaps they get passed over in favour of the more popular, in some cases higher value sounds. I also think a lot of folk tend to post the same old same old cos it's still going earn kudos and get lot's of hits......if that's your thing. For my part many of my records weren't, at least at the time of posting them, duplicated on there, although they probably are now. They are/were always completely random picks with no effort made to cherry pick from whichever part of my collection is around the turntable at the time (this is mainly because there are no "cherries" to pick out in my collection). I reckon if I were to actually make an effort to post videos more frequently and try to select things that hadn't already been posted I would still easily be able to keep going doing just that for years.......there's just so much music on vinyl out there.
