Awhile back, I posted a few tips on how to effectively find PDFs online. With big name brand search engines like Google, Yahoo! and MSN, you could find any PDF by simply adjusting a few search settings and boolean terms. You don't need to do all that anymore. PDF search engines are emerging to eliminate that task. Here's a brief look.
Data-Sheet (beta)
This PDF search engine lets you find and download data sheets, reports, and ebooks. Data-Sheet comes equipped with Popular and Recent datasheets search options to narrow your search, and the ability to add the search box to your browser. One thing to note: along with your results, Data-Sheet also gives you image search results with links that, unfortunately, don’t link to the sites, but launch a browser view of the image instead.
