A while ago I was searching for the manual of my new LG Cookie Pep Mobile. I didn't get the manual from LG junk website, so I tried Gooogling and found a list of answers where I came through websites which have millions of PDf files around the world! I have listed two of the most usefull and clean websites among them. Theses websites have millions of PDF files to search on.
- Pdf Database
The first one I would recommend is the www.Pdfdatabase.com
As on 11-04-2010 this website have 16893903 files in their database!! That's a lot of files.
You can also submit your PDF links to this website here
Then www.PdfQueen.com is also a good option. However, this website doesn't have any link to contact the admin or about page or nothing, I just saw a "Abuse" page, thats all.
- Ebookee.com - This site lots of categories and advance search options for diff categories.
- Pdf.rapid4me.com - This is a dedicated PDF sub division of Rapid4me search engine
- Pdfone.com - This is just a blog, but have lots of usefull eBook PDf files for you!
- Data-sheet.net - This site is under beta label and it is dedicated to PDF manual search engine.
- Filedigg.com - Apart from PDF this website also have lots of other useful resources.
