The changes in the banking industry over the last decade have spawned a greatly expanded vocabulary, and ``Barron's Business Guides'' has responded with a dictionary which will be of great service to bankers, business and management professionals, attorneys, investors, and librarians. The diminutive size of the book (4 3/16 x 7) belies its breadth. Not only are cogent definitions included, but author Fitch wisely adds longer discussions where needed. He summarizes key banking- and securities-related laws and provides a table of acronyms as well as extensive cross references. The financial community will find this an invaluable reference tool, as will libraries with business collections of any depth.-- Joan Pedzich, Harris, Beach & Wilcox Lib., Rochester, N.Y.
