Columbia University in New York City has published a revised edition of its comprehensive HIV/AIDS handbook, intended for those at risk of HIV infection and people currently living with the virus. You can download the 116-page document for free using the link here.

The Columbia Handbook on HIV and AIDS combines and updates two previous works originally published by Simon & Schuster (Pocket Books): The Essential AIDS Fact Book and The Essential HIV Treatment Fact Book. The new handbook, which some have called an AIDS bible, offers key information on HIV transmission and prevention methods plus the basics of HIV treatment.

The handbook was written by Laura Pinsky, MSW, founder and director of Columbia’s Gay Health Advocacy Project (GHAP) and a contributing AIDSmeds writer, along with Paul Harding Douglas, the former codirector of GHAP who died in 1995. “This is an important book, up-to-date, extraordinarily comprehensive,” writes Jeffrey Laurence, the director of the New York Hospital AIDS Virus Research Laboratory.
