PREFACE 
THIS Bibliography is based upon an incomplete manu- 
script for the years 1534-1892, by the late C. Fox- 
Strangways, F.G.S. This has been checked and con- 
siderably amplified. In connection with the old books dealing 
with Spas, etc., Fox-Strangways spent a considerable time at 
the British Museum, and, as a result, few additions have had to 
be made to that section of his work. For the entries for the 
years 1893-1914 (from page 254 to the end) I am responsible. 
The completion of this Bibliography in the comparatively 
short time of five years has been rendered possible by the 
fact that I have in my possession complete sets of most of the 
geological and natural history publications which contain 
papers on Yorkshire. I have also had access to many rare 
books, pamphlets and maps, and have paid many visits to 
the libraries in London and elsewhere, especially with regard 
to the earlier publications. To all those who have so 
willingly helped, I am very grateful ; especially to Mr. George 
Barrow, of H.M. Geological Survey, for his pains in com- 
pleting and amplifying the information Fox-Strangways had 
prepared in reference to the maps of the Geological Survey 
(pages 477-502).
