The PDF Catch looks like an amazing resource! Essentially the user types in a topic and various PDF results are caught about that topic (hence the name PDF Catch). For example, I entered "8th Grade Reading List" and found a plethora of reading lists from various sources.
*PDF Catch is beneficial because it instantly finds substantial content and not just websites that will have surface information or will try to sell content.
*I could see using PDF Catch to find curriculum or professional development information or resources. Rather than purusing a myriad of websites, I could instantly find significant content published or released by sources.[/list][/list][/list]
*PDF Catch seems to collect reliable information as well. In trying to use this with the topic of Middle School Professional Development, I caught a number of PDF's that were from reputable sources.
