Roy Tennant discusses how library services can be improved by concentrating resources and data in a centralized location while also diffusing library holdings and links to services in places where users search for information online. Some benefits of concentration include improved search ranking, increased holdings and usage data to mine, better user-contributed content through sharing and improvements, and the ability to attract more attention and redirect users. Benefits of diffusion include syndicating library holdings wherever people search online, allowing smaller libraries to participate alongside larger ones, and creating more paths for users to discover library resources.
