still avail: "Best Bread Ever" by Charles Van Over.
As most of the decently-priced/discounted used copies of bread cookbooks have disappeared from Amazon (only full-price copies remain)...
I thought I'd pass on this tidbit about a classic bread book (has both commercially yeasted and sourdough formulas) that is still available for US $8 to $11 used.
"Best Bread Ever" by Charles Van Over. Hardcover, copyright 1997.
His instructions for starting a wild sourdough starter on page 176 using orange juice, similar to the famous instructions here on TFL: http://www.thefreshloaf.com/10901/pineapple-juice-solution-part-2
