Now this is an interesting find: a search engine for PDFs, DOCs and PPTs. Hat tip to Simon Fodden over at Slaw for this gem, called Osun Document Search.  The stipped-down, Google-like search page has a search box with buttons for PDFs, DOCs and PPTs. Results pages also look suspiciously similar to a Google page, except that they are populated exclusively with documents. Popular “hot docs” are listed on the right.

Mr. Fodden has devoted some time and energy into getting the back story on Osun and believes that it may be relying on Google’s own document search capabilities, and then merely re-packaging them into a document-only results format. In any event, the site is of value even if only for its format of cutting out the websites when you are only interested in documents.
