Library Journal deemed the first edition of Diane Kovacs' groundbreaking guide "an essential purchase for all libraries." This edition covers over 15 subject areas, including jobs and employment, business, medicine, law, social science, engineering, computer science, physical science, earth sciences, arts and humanities, and more. Kovacs extensively updates her coverage of Web collection development resources, Web-accessible licening resources, and real-life e-library success stories. Chapters are dedicated to e-library management and maintentance, including guidance on negotiating e-resource licenses and collection analysis. For each subject area, core collection development tools have been expanded to include Web 2.0 related services and government documents. A bonus companion Web site--available only to purchasers of the book--features ready-made, annotated links to all the sites in the book's recommended core reference collections in each subject area that readers can import into their library's Web site or OPAC.
