HI,
I think around 4500 but, truthfully, I've lost count. At a certain point you don't count records but measure the amount of feet of shelf space the collection takes. I do it this way.
Count the number of albums on a typical shelf. Then divide that number by the length of the shelf in feet. This gives the number of albums per foot on a typical shelf (the reference foot). Then determine the total number of shelf feet the collection requires. Then multiply the number of albums in the reference foot by the number of feet of shelf space. It's not exact but does give a rough number.
Numbers don't mean a lot to me. Quality does, though. All mine are in great condition, vacuum washed and Lasted.
100% LP's. About half were bought used. Roughly 50% are classical. Then jazz, then rock and roll (only 60's and 70's, please) then a mixture of East Indian Classical, electronic, folk, and Misc. Some of the Misc. collection are spectacular including Sheffields (I have the complete collection) steam locomotives, tugboats, thunder storms, Tibetan Bells and other sound effects. I love pure sound.
