Digitization of books, particularly those that are out-of-print, in projects such as Google Books provides resources for library and other online users. Due to their holdings of valuable material, some libraries are important partners for search engines such as Google in realizing the potential of such projects and have received reciprocal benefits in cases where they have negotiated effectively. As the prominence of and reliance on the Internet has grown, library services have moved the emphasis from mainly providing print resources to providing more computers and more Internet access. Libraries face a number of challenges in adapting to new ways of information seeking that may stress convenience over quality, reducing the priority of information literacy skills. The potential decline in library usage, particularly reference services, puts the necessity for these services in doubt.
