Librarians are in the business of serving the public. Perhaps the public happens to be those who live in a particular city or county, or study at a college or university, or work at a certain organization. No matter where librarians work, they have clientele whose needs for information and entertainment need to be met. Some would think that librarians would know what the public wants. Librarians have some ideas, mostly based on anecdotal information (for example, what someone asks for at the desk), but they do precious little with the statistical gold mine that is accumulated by many of the computer systems. Integrated library systems tend to do well reporting aggregate numbers of books circulated, but why isn't there an option to order search results based on popularity? One of the most familiar services based on popularity is Google. Google's PageRank [TM] system is basically an algorithm for determining the relative popularity of web pages. Search results are then ranked based on that computed value. This article briefly discusses popularity in library information.
