Google Books: Ethics
Started in 1996, the goal was to make digital libraries work. If a book is out of copyright, or the publisher has given Google permission, you’ll be able to see a preview of the book, and in some cases the entire text. If it’s in the public domain, you’re free to download a PDF copy. The following are a couple of examples of what you can find online.

Ethics Resource Center
This reputable site has an ethics toolkit, which includes a glossary, definition of values, writing tips for creating an effective code of conduct, the PLUS ethical decision making model, and more. Webcasts, national surveys, articles, and federal policies are also listed.

The Internet Encyclopedia of Philosophy
The purpose of the IEP is to provide detailed, scholarly information on key topics and philosophers in all areas of philosophy. The Encyclopedia is free of charge and available to all users of the Internet world-wide. The present staff of 25 editors and approximately 200 authors hold doctorate degrees and are professors at colleges and universities around the world, most notably from the United States, Great Britain, and Australia. The submission and review process of articles is the same as that with printed philosophy journals, books and reference works. The authors are specialists in the areas in which they write, and are frequently leading authorities. Submissions are peer reviewed by specialists according to strict criteria.
