Although there’s no shortage of search engines for PDFs around, it’s always nice to have one which is as fast and concise as this one at hand. PDFSB has been built in a very tidy way, and there’s just nothing that could distract or divert you from using the site as intended. PDFSB has got a simple search interface, letting you provide the name of these titles you’re interested in, and also to specify the number of pages that they should have (a great way to weed out unrelated matches with little effort).
Of course, it’s also possible to search for PDF books by author. You just supply the name of the writer who penned the book when prompted for the title, and it will be duly used when looking for suitable matches.
Additionally, you’re allowed to choose the language you need your PDFs to be in. Eight are currently supported, and these include not only English, Spanish, French and German but also some languages that are seldom taken into account such as Indonesian.
As it stands today, over five million titles are indexed by PDFSB.com. These can all be downloaded for free.
