I just checked eBay, like I said LOTS to choose from.
If you decide to go for the Blue book, then read carefully. The one for sale right now is the 1928 version which has fewer songs than the later ones. What you want to look for is the book entitled The New Blue Book Of Favorite Songs. There is one in the lot entitled VOCAL MUSIC LOT OF 40 Songbooks & SHEET MUSIC 1910-2001 priced at $4.99 and well worth the money.
