author
Best known for richly detailed books on London’s past, this writer and editor worked closely with the City’s archives and turned historical records into vivid reading. Project Gutenberg also lists a very different title under R. Sharpley: a sketchbook of scenes along the Thames.

by R. (Reginald) Sharpley
R. (Reginald) Sharpley is a somewhat elusive figure in the historical record available online, so the safest confirmed picture comes from library and ebook catalogs. Project Gutenberg lists The Thames: A Sketch-Book under Sharpley, R. (Reginald), a work of illustrated travel and landscape impressions centered on the River Thames.
A closely related but better-documented name is Reginald R. Sharpe (Reginald Robinson Sharpe, 1848–1925), who is credited by major library catalogs with substantial historical works including London and the Kingdom and editions of important City of London records preserved at Guildhall. Those books suggest a writer deeply engaged with London history, civic documents, and the texture of the city’s past.
Because sources do not clearly prove that every work under "R. Sharpley" belongs to the same person, it is best to read this attribution with a little caution. What can be said with confidence is that the name is associated with books that bring together place, history, and careful observation.
