Visit the Google Books website (see Resources).
Type the title of the book you are interested in into the search field at the top of the page. If you do not have a title in mind, then type a keyword for a subject that interests you. Click the “Search Books” button. The site returns a list of books that match the search term.
Click the title of the book you want. This action opens the book in a PDF format. If the book is downloadable, you will have a full view of all the pages in the book and there will be a download button at the top right corner of the page.
Click the download button. This button, sometimes with “Download” on the right side, usually has an arrow pointing down. You may be able to select a file format from a list but this will depend on the formats available for the book you wish to download. Select a file format that you are comfortable with.
Choose a location for the file in the “Save as” dialog box that pops up. Click the “Save” button.
Go to the location where the file is saved. Double-click the file to open and read it.
