Stock warrants

Do you know of an authoritative and reasonably objective book on stock purchase warrants? --

Probably the most definitive book on stock warrants is Sidney Fried's "Fortune Building in the 70's With Common Stock Warrants & Low Price Stocks" (R. H. M. Associates, 417 Northern Boulevard, Great Neck, N.Y. 10081). While this book may be out of date in places, the concepts remain valid. For up-to-date information, R. H. M. Associates publishes a "Survey of Warrants, Options and Low-Price Stocks" as a weekly newsletter. Warrants to buy stocks are traded on the exchanges and over the counter and offer speculative but highly leveraged opportunities for investors. But before plunging, learn about the prices at which stocks may be bought and, particularly, the expiration date for warrants.
