Managing Gigabytes: Compressing and Indexing Documents and Images is a treasure trove of theory, practical illustration, and general discussion on the topic of technical interest. Ian Witten, Alistair Moffat, and Timothy Bell have updated their original work with this second edition even more impressive. This version adds new techniques such as block-sorting, new indexing techniques, new strategies lossless compression, and other elements to the mix. In short, this work is a comprehensive summary of text and image compression, indexing, and query techniques. Historical development of relevant algorithms both woven with practical discussion of challenges, pitfalls, and specific solutions. This title is a textbook style exposition on the topic, with information organized very clearly on topics such as compression, indexing, and so forth. Plain Topics covered: Text compression models, including Huffman, LZW, and their variants, the trend in information management, index creation and compression, image compression, performance issues, and implementation of the overall system.
