Students of all ages often wish they could have an electronic version of a book on study skills, a reference book, a book on math, a foreign language, or a book for learning English. Of course, you can always buy a download from the major vendors on the internet, but often we just need these books for a few weeks. You can gain access to lots of these electronic learning material for free if you have a library card. Most libraries nowadays allow you to download an e-book or audiobook for a three- or four-week period. It's just like checking out a book at the library. The only difference is that you check it out on line, and download the book to your computer. After the borrowing period, the library's software simply removes the electronic source from your computer. Ask your local librarian about the electronic services available.
