BIBLIOGRAPHY OF YORKSHIRE GEOLOGY, 1915. 
By T. Sheppard, M.Sc, F.G.S. 
Now that the Bibliography of Yorkshire from 1534 to 1914 has 
been published, as Volume XVIII. of our Proceedings, it seems desirable 
that a Yorkshire list should appear amiually in our Proceedings, in 
order that the Bibliography may be kept up-to-date. These lists 
formerly appeared in The Naturalist, but in future it is proposed only 
to print in that journal particulars of the items referring to the geology 
of the northern counties, with the exception of Yorkshire. 
At the same time it is proposed to include particulars of any items 
that may have been omitted from the list in Volume XVIII. If, 
therefore, any of our readers notice any items which ought to have 
been included, perhaps they will kindly advise me.
