I received several comments to my first list of twenty authors to add to your reading list, mostly suggesting additional authors I had not mentioned. In one case I responded that I actually had the suggested author on my list but I lost it when I reduced the list to only twenty names.
Since then I have realized that I have more than twenty additional authors who should be recognized and added to all those more traditional reading lists. For now I offer yet another twenty valuable writers I have found stimulating and I highly recommend them to everyone.
You might not recognize some of the authors but several are actually quite well known and often highly rewarded writers. Notice that this list focuses on writers who probably did not write originally in English. Of course translations are generally available but I also want to encourage those who are able to read the original language, even if with great difficulty, to read the original as it was written by the author.
