In this nicely annotated webography, Leftley (chartered librarian, U. of Oxford) picks the most reliable, stable and informative sites from around the world, gives title, URL, owner or maintainer, server location and a full description. Logically sorted into general resources, resources by category, and indexes, sites include libraries and their catalogues, bibliographies, subject gateways, awareness services, organizations, and teaching-related sites, and categories including cartography, cybergeography, earth sciences, environment, metrology, population and remote sensing. Leftley even includes indices by site name, URL and keyword for those of us low on organic memory. Annotation ©2004 Book News, Inc., Portland, OR (booknews.com)
