I was hunting for an online reference to an article by L. Ron Hubbard and I remembered that the article is in the Scientology Handbook. I went to the book's web site and found an index of online articles from the Scientology Handbook. It's not the entire book, the book is huge, but there is a tremendous amount of the book on the site.
It also made me think that this would be a good starting place for someone who wants to know what Scientology is. Because Scientology is a practical religion, a religion that is all about living, solving the problems of life and improving situations, the best way to find out more about it is to read the actual methods it provides for handling life and its situations. The index on the Scientology Handbook site is a perfect place to start.
