Books in the public domain

• Google Books - Google provides an embed code for each book in their database and this code can be pasted into any website, blog or wiki to allow your students to read from the text directly from your class site. Some Google Books can also be downloaded as a pdf or ePub format that can be read directly on an e-reader or handheld or tablet device.
• Google Search - When conducting a search online, simply add the term eBook or eText to the search terms. This simple addition will point your search in a direction that will find eBooks that you can then use in your classroom.
• Project Gutenberg - Similar to Google Books, Project Gutenberg is beginning the process of making books available online for download from their database in a number of eBook formats.
• LibriVox - An eBook isn't just downloadable text, LibriVox offers audio files for download of books that are available in the public domain. Simply search for a book by title or author and download the audio file.
