Thanks for compiling and posting this!
Years ago when I was a early teenager I stumbled upon a few of the Martian series. They were a great read but I didn't realize there was more of them until now. This series and the Tarzan books should keep me busy for awhile.
Also the quality of the epub file is excellent! I went to the bookcase and pulled out my old hardbacks (one's dated 1929). While thumbing through the book, I noticed the illustrations and I was surprised to see the epub also had the same artwork. Neat! Much better than the TXT files I downloaded from Project Gutenberg years ago.
Now all I need is a nice e-reader so I can sit in my comfy chair while reading.
