If you have ever tried to search for books using the most common search engines, then you know that actually finding one can be tough. Thankfully, there is Pdfgeni.com. Through this search engine, you’ll be able to search the web for PDF files, and nothing else. This allows you to type in the key words that describe the book you are looking for, and see what’s available. After you search, you’ll be presented with a listing of books and PDF files that matched your search criteria. One great thing about the site is that you can preview the files before downloading them. This allows you to see if the book you found is the one you were looking for. The preview loads really quickly and should serve as an alternative for anyone who doesn’t want to download the texts, and needs them for quick reference. Allowing to preview the files is a great feature that makes the site a lot more useful.
