The first editions of these are sold out long ago, but now they will be released as “ultimate editions” both in hardcover and paperback. The first volume is available in hardcover right now. You can order it here.
I’ve collected the few letters I could find, written to Robert E. Howard or to his father, Dr. Isaac M. Howard below. One day I hope it would be possible to be able to show every letter and typescript that Howard wrote.
If you have digital copies of any letters I would really appreciate it if I could get a copy to display here. Please contact me.
