I appologize if this information is already known and somewhere on the site that I did not see. I've checked but didn't see any information about it so I decided to post this just in case anyone is interested:
If you go to books.google.com and search for "Earl Derr Biggers" (with the quotes) and then at the left choose "Free Google eBooks", you'll see various writings by Earl Derr Biggers including "The Agony Column", "Seven Keys to Baldpate", and "Love Insurance" all of which are free to read. I have not read them but I found it nice that they were freely available on Google Books.
