JV.B. — The List represents the minimum bibliographical equipment 

 of a library professing to specialize in any of the following departments 

 of knowledge. It is a selection from the " Class Catalogue of Current 

 Serial Digests, etc.," issued by the Library Association in 19 12, revised 

 and extended. The classification is that of the Library of Congress, ex- 

 cept that Z Bibliography has been transferred to A. As a rule German 

 periodicals have been included only where no suitable substitute in another 

 language could be found. 



AA. — Universal Bibliography. 



Union Lists of Periodicals. 



As there is no printed Union List of Periodicals of the United Kingdom, infor- 

 mation must besought in (i) the lists prefixed to the Subject Indexes, 1800-1900, published 

 by the Royal Society (B.J. Q) ; (ii) the local Union Lists published by Manchester 

 (1898); Cambridge (1906-1914), and Oxford (1913) ; (iii) the catalogues of periodicals 

 published by various institutions, e.g. the British Museum; Royal Society; London 

 University ; Patent Office, etc. Where these sources fail, application should be made 

 to the Keeper of the Printed Books, British Museum, for the desired information.
