DejaVu is a data format designed specifically for compressing and
displaying scanned images of printed material, such as book pages, a
task at which it excels. Scanned materials for this course will be
made available in
DejaVu (.djvu) format, which is smaller, faster and
more flexible than Portable Document Format (.pdf). Each image of a
page also contains a hidden layer of text built by "optical character
recognition" (OCR). This enables you to search through the text of
the work you are reading, or to copy the text easily into another
document.
