Over the vacation I reorganised my office, including adding a bookcase specifically for the 60 or so books I have on various aspects of information retrieval and search. In the process I updated the list of books on the Enterprise Search book website, highlighting eight which I regard as a core collection for search managers. These are listed here for convenience. All the books have been reviewed on the Intranet Focus blog and some have a dedicated website. They cover the spectrum from a deep dive into the technology, the optimisation the user experience, search evaluation and text analytics and mining. With a couple of exceptions they have all ben published in the last two years, which indicates the level of interest in the subject. Publishers publish to make a profit!
