Book excerpt: The Internet is a mixed blessing for libraries and librarians. On the one hand, it provides opportunities to add services and expand collections; on the other, it increases user expectations and contributes to techno-stress. Today, the Net is challenging the librarian's ability to select, threatening the survival of the book, necessitating continuous retraining, presenting unique problems of access and preservation, putting new demands on budgets, and embroiling information professionals in legal controversies. In "Net Effects, Marylaine Block examines the issues and brings together a wealth of insights, war stories, and solutions. Nearly 50 articles by dozens of imaginative librarians--expertly selected and annotated by the editor--suggest practical and creative ways to deal with the range of Internet "side effects," regain control of the library, and avoid being blindsided by technology again.
