Record heads, check this out, the Collector's Guide to American Recordings, 1895-1929, copyright 1949, I assume it is long out of print.   6 inches by 9 inches, 198 pages.  The book lists classical artists: name, companies the artist recorded for, record name and number, very easy to use!  Book shows wear but in nice shape for a 70 year old paperback!   A great reference guide, I have no idea where you would get another one, go for it!

Shipping to USA addresses only.  $4.75 media mail postage and shipping fee.  See my store for more antique phonograph records and items, and thanks for lookibng!
