DjVu:
DjVu is a relatively new technology developed by AT&T research labs, and licensed to LizardTech for commercialization. It allows much greater file compression than other formats, and also allows searchable text and image files, similar to PDF. It is supported by browser plugins, available for most operating systems. In order for users to view DjVu information, they need to download and install the plugins. The document then appears in a browser window, similar to PDF files.
Advantages
Small file size — A typical PDF of 200K can be reduced to 50K, saving download time. A 3.75 MB TIF image that would be 160K as a JPG file can be reduced to 65K.
Searchable text & image files. Very similar to PDF documents.
Disadvantages
Needs a special plugin. This plugin is self-installing for Windows, however, so it isn't difficult to configure.
Proprietary format which doesn't have a large user base.
Searchable text is not correctable at this point, whatever the program recognizes as text is inserted into the document.
