Our humble history began in 1931 by publishing a pricing book for electrical contractors that would eventually be named the Biddle Book.  Since then we expanded into multiple industries and grew from a simple publishing company into a complete source of business data for contractors, distributors and manufacturers alike.  Our 20,000+ customers rely on one or more of our products daily.
