If you’re interested in the academic side of search, chances are you’ve come across the work of Marti Hearst, a professor at Berkeley’s School of Information. Her work covers everything from search engines, search interfaces, social technology, information visualization and web usability. Her book, Search User Interfaces, came out late last year and is a great resource for anyone interested in the information seeking process and how users interact with search and search results. Better yet, the text of the entire book is available free online.
