Behind each of the six editions of Doody’s Core Titles is a dedicated group of health sciences librarians who volunteer their time and expertise to produce this up-to-date collection development resource for their peers. Doody’s Core Titles 2009 boasted the largest contingent yet -- 124 librarians from more than 50 health sciences libraries from several countries worked to select and score the must-have titles in 121 specialties. Without the energy, insight, hard work, and good will of the librarian selectors, Doody’s Core Titles simply wouldn’t exist, and the 4,000 librarians around the world who rely on it would have to search for expert help with their collection development.
