The 260-page book Arnold Bennett and H.G. Wells: a record of a personal and a literary friendship (1960, Hart-Davis / University of Illinois Press) is sadly not available in any library in the Potteries. It’s not on the Staffordshire or Keele catalogues, and Stoke Local Archives is listing it as “0, reservations unavailable” which seems to imply “stolen or lost”. According to Copac the nearest copy is down at Birmingham University.
However, I’m pleased to see it’s actually online at Archive.org for free: Arnold Bennett and H. G. Wells: a record of a personal and a literary friendship. It’s been scanned and placed online by the University of Florida. Good for them. There’s even a Kindle ereader edition. The letters are annotated.
Since the book has been placed “Out of copyright”, here are the front portrait pictures, extracted by me at their highest resolution. Feel free to re-use.
