Sanskrit Digital Library

http://sanskritlibrary.org/
Above link will take you to a collaborative site, created by several German and American universities, with the support of National Science Foundation. In their own words, these Universities are dedicated to:
"The Sanskrit Library is dedicated to facilitating philological research and education in Vedic and Classical Sanskrit language and literature by documenting,collecting, preserving, and publishing oral, written, and printed texts in digital form, and by developing innovative research and educational tools. Current research involves linguistic issues in encoding, computational phonology and morphology, OCR for Indic scripts, and markup of digitized Sanskrit lexica." To checkout their work,just go to the "Texts" link and simply click "submit" (while options are shown as "ALL"). You will see a collection of Vedas, Upanishads, Sutras, Ramayana, Mahabharata, Sankaracharya's works, etc. When you click on any of the listed links, the detail page opens. The "Text" button on top of the page gives you the text of the book in Devanagari script. Within the text, clicking on any sentence opens another "reader companion" that shows the pronunciation for that sentence. Alternatively, you can go to the "web page" link in each work and open the entire text written in English like script.
Earlier there where works of Indian Institute of Science but it was mostly limited to scanned versions of Sanskrit works, not total digital creations like this one. Very impressive indeed!
