chapters.indigo does offer it through its website, but that doesn't guarantee it will be available in stores.
I have the latest update as well as the 1997 version. The new revision is a whopping 938 pages (up from 698 since 1997), I hope your friend has a good back. Contents include sections devoted to different eras (1874-1945, 1946-1967 and 1968-2002). Those sections include breakout chapters on stars of the past and present such as Bill Tilden, Althea Gibson, Rod Laver, the "Four Queens" (King, Court, Evert, Goolagong), and the Williams sisters. In the next section you will find chapters devoted to the 4 major championships, followed by sections titled "International Play" (Davis Cup, Fed Cup, Olympics, etc.), "Biographies" which are about 1-page summaries of the achievements of notable players and other contenders, "The Registers" which provide yearly records for notable players, and the "Appendix" which details information regarding the Hall of Fame, rankings, the associations (ATP/WTA), World Team Tennis and more.
My only regret is that the new version does not contain an index (unless it's hiding in those 1000 pages!). But this is the only tennis history volume of consequence.
