Not published?
The third impression of John Clare, as well as first editions of Arnold, Donne and Flecker, probably published in about 1968/69, all list an edition of the work of Charles Wesley among 14-16 other titles as also in this series
. This title was not listed in later small books, I have not seen a copy, and I can't find one listed in any library. Perhaps the volume was in preparation but was not finished. I could imagine that Carr, whose father was a Methodist preacher, might have wanted to publish the poetry of a founder of Methodism, but I wonder why he didn't? If you have a copy, please let me know.
