Classic Clinical Reference Now Continuously Updated

Charlottesville, VA, September 26, 2006—Unbound Medicine, a leading provider of knowledge management solutions and mobile information resources for healthcare, today announced the release of The Merck Manual for Mobile Devices in partnership with Merck & Co., Inc. Clinicians now can refer to a continually updated Merck Manual from any location using a personal digital assistant (PDA) or a wireless device.

Since publication of the first edition in 1899, clinicians worldwide have counted on The Merck Manual for concise information about diagnosis and treatment. Unbound Medicine’s new release contains the unabridged contents of the just-published 18th edition of The Merck Manual—the work of more than 300 expert authors. Coverage of important areas such as psychiatry, gynecology, pediatrics, alternative medicine, poisoning, and minor trauma takes The Merck Manual beyond the bounds of typical general medicine texts, reflecting the needs and interests of today’s primary care and family medicine practitioners. In keeping with a commitment to current and practical content, material has been added on important and timely topics such as avian flu and biological warfare.

Unlike a print book, The Merck Manual for Mobile Devices will be continuously updated to keep clinicians informed of the latest developments that impact practice. The unique Unbound™ Platform will deliver bi-monthly updates automatically to subscribers when they synchronize their handheld devices.

“We have always seen The Merck Manual as a compact and easy-to-use reference for physicians, medical students, physicians' assistants, pharmacists, and other healthcare professionals”, said Robert S. Porter, MD, Editor of The Merck Manual. “By partnering with Unbound Medicine, we are able to make the manual more accessible than ever. We especially like the fact that the Unbound Platform optimizes presentation of the content so that clinicians have the option of using a PDA or a wireless device like a Treo™, Smartphone, or BlackBerry™.”

“We are excited to participate in the transformation of a book with such a long tradition into a mobile and continually updated reference for 21st century clinicians,” said Bill Detmer, MD, President and CEO of Unbound Medicine. “The decision of the Merck editors to provide regular updates recognizes the need of frontline healthcare providers to have quick access to current information when they are at the point of care.”

The Merck Manual for Mobile Devices will premiere this week at the Scientific Assembly of the American Academy of Family Physicians in Washington, D.C. For more information about The Merck Manual for Mobile Devices go to www.unboundmedicine.com/merckmanual.
