DjVu is a file format that bundles together multi-page documents in a manner similar to a PDF file with the advantage of quicker transmission time for large files. The compression techniques used enable even lengthy books to be accessible in one djvu file.

Viewing DjVu files requires the DjVu Browser Plug-in which will allow you to view and navigate a DjVu document, and zoom and pan in real time. You can also search the text of a DjVu document if optical character recognition (OCR) was performed or if the document was converted from an electronic source.
