via PREFACE 



are given to the number under which the periodical is catalogued. 

 Cross-references from the names of the more important editors have 

 been made in a similar manner. When the change in the title of a 

 periodical is of only minor importance, it is indicated by the use of 

 round or brace brackets. 



Three kinds of BRACKETS are used in the Catalogue : (a) round 

 brackets ( ), indicating that the words enclosed appear on the title- 

 pages of the later volumes, but not on the earlier ones : (6) brace brackets 

 { }, indicating that the words enclosed appeared on the title-pages of 

 the early volumes, but not on the later ones ; and (c) square brackets 

 [ ], indicating that the information contained between them is supplied 

 by the cataloguers. An arrow > after a volume number or a date 

 indicates that the Library set of the periodical is ' In progress '. 



The SOCIETY INDEX shows what publications of a particular Society are 

 in the Library. The number after each entry refers to the corresponding 

 number in the main part of the Catalogue. An arrow after the 

 number signifies that the Library set of the periodical is ' In progress '. 

 This index includes various Government Departments, Universities, 

 Colleges, and similar public bodies. In order to facilitate reference 

 a duplicate entry has been made under the name of the town in which 

 the head-quarters of each Society are situated. 



In the compilation of this catalogue much valuable information has 

 been obtained from the 'British Museum Catalogue of Printed Books', 

 sections ' Academies ' and ' Periodical Publications '. The ' Catalogue 

 of Scientific and Technical Periodicals ' by H. C. Bolton, published by 

 the Smithsonian Institution, has also been of very great assistance. 



The Catalogue has been compiled by Mr. Luxmoore Newcombe, 

 Sub- Librarian of University College, London, and Mr. L. Ellston, M.A. 

 The thanks of the Committee are due to these two gentlemen for the 

 care and ability which they have devoted to the task. The Committee 

 also wish to express high appreciation of the manner in which the staff of 

 the Oxford University Press have carried out their share of the work.
