Yep. sometimes you need pdf document and you know whatever you website visit and do search you always get same result - inaccurate , some documents will pop up in search results , when you check them instantly understand that just some crap just discovered , you will leave that search engine and try another and another and then ANOTHER! Too small website , too small database, no one cares about user, adware, popups you'll get it all!
Finally then you find document you need it will offer and download which will install an toolbar , even more... illegal adware. I did such searches i'm educated person. I NEED INFORMATION. I like to read - Yes.
After some time when i got access to bad ass powerful server , i'm with my friend , started of development pdf documents scraper based on some open source code, lately after few months we released public version of pdfcrawler.com
Following Google guidelines and legal scraping techniques after few months we able to harvest over 16K pdf files , we even sorted them by popularity from searches made on website and general info like download count on source. Right now we have over 2 million quality pdf documents as I write this article.
So we basically have solved simple task, to have huge database of pdf files IN ONE PLACE AND HOSTED LOCALLY!
