Google is a great company, so we can do many useful and interesting things using Google and its services. In this article, Sanliang Fan will teach you how to use Google Docs to create your own online PDF library. PDF is my favorite e-book format, and it has recently been approved as an ISO international standard, so you may have hundreds of PDF e-books and documents just like me. So, why not turn your e-books into an online library? This way, it saves disk space and allows you to read anytime, anywhere. First, you need a Google Docs account. Then, log in to your Google Docs, and in the left toolbar, select sequentially: Organize items, PDF. Hover your mouse cursor over the PDF option, right-click, and select the upload option. There are two ways to upload PDF e-books: one is to upload from your local disk, and the other is to enter the URL of the PDF e-book, and Google Docs will automatically download it to the server.
