Note:
Edited by Dr Richard Wilson, B.A. (1928)
Evidently Wilson is the series editor. Both volumes in the database December 2018 credit another person for the arrangement of the particular work. (Wilson is also the compiler of one 1928 volume in the "Teaching of English" series edited by Sir Henry Newbolt.)
'Messrs Nelson, Edinburgh, have issued in their "Books Within Books" series of reprints edited by Dr Richard Wilsohn, B.A., five volumes (each 1s. net), containing skilfully adapted extracts from well-known works of eminent authors in English literature, the selected passages forming a complete story."
