I encountered this a while back and have to say that I was impressed by a very nice e-version of all of H.P. Lovecraft’s writings neatly compiled by a young lady (Ruth) who goes by the moniker of Cthulhu Chick. I strongly encourage anyone interested in enjoying the Cthulhu Mythos for the first (or even fiftieth) time to give Ruth’s website a look. She has kindly gone to the trouble of compiling various digital formats for you to kick back with.
These files work especially well on Kindle, iPad, and Android tablets so give them a look and be sure to say thanks for all the hard work that went into what is truly a spectacular collection.
Oh, and did I mention it’s completely free?
