Google’s robots do a outstanding job at finding and indexing web content. This can be good and bad. It is good because there is a very high chance of finding just what you need. Bad because you may need to weed through hundreds of results. However by using just a simple advanced search technique your odds drastically increase. When using Google’s main search specify both the title and file type or ISBN and file type like this:
filetype:pdf “textbook title”
filetype:pdf “ISBN #”
In addition to general searches Google has a search just for eBooks. That search is here:
With just a little practice you should be able to find PDF versions of your needed textbooks online.
Important: We need the text book publishers to stay in business creating textbooks so please honor any copyrighted material restrictions.
