The task of finding specific PDF files on the Internet has become increasingly easier, thanks to a new search engine created specifically for PDF content.
The tool is PDF Search Engine and it's a great addition to your present DAO resources.
The simplicity of using PDF Search Engine is what makes it solid tool. The web-based interface is somewhat Googlesque, as it mimics the minimalistic style and single text field area. Users simply type in the term they want to search for and with the press of a button, search results instantaneously appear, ready to be downloaded. Firefox users will all be pleased with the free downloadable extension that is also available.
I personally use a few different means to search for PDF assets, and the addition of this new tool is certainly welcome. Using advance google search seems to be the primary method most people use. I think this is just the beginning of format-specific search engines, which will ultimately have a huge effect on DAO strategies.
