Scribd is an online platform that lets you publish, share and discover documents on the Web. Scribd works like YouTube, but you browse and upload texts instead of videos. Started in 2007, usage has grown dramatically and now it is the largest service of its kind with more than 50,000 documents uploaded every day to the site. Contributors include magazines and newspapers such as the New York Times.

To use Scribd, just pick a username and password and click the Upload tab. Scribd's iPaper document reader transforms PDF, image, Word, PowerPoint and many other file formats into an attractive Flash format. You can add descriptions, categories and tags, and each word is indexed for search engine optimization so your work can be discovered by web searches. You can also limit access to your work if you wish.

What's more, Scribd's iPaper document viewer can be embedded in any web site by copying and pasting a short snippet of code.
