We have owned the print format of the Dictionary of Scientific Biography for many years, and can access it in the OhioLINK Electronic Books Center. We now subscribe to the online version at the publisher's website (Gale/Cengage), part of the Gale Virtual Reference Library, where searching and browsing functions are very nicely supported. Link to it from the OBIS catalog record. Composed of 18 large print volumes, the title "Dictionary" does not do justice to this comprehensive encyclopedic work. Take time to browse the index volume and jump from one entry to another, and you will gain a new understanding of the development of science and the people who advanced that knowledge throughout centuries. Simply browsing the list of illustrations indicates the wide breadth of scientific information represented in the work. Go discover!
