PREFACE. 



sake of systematic arrangement and as a convenience to the 

 readers. 



The present list is chiefly confined to Bibliographies, but 

 it may perhaps be as well to point out that much useful 

 bibliographical assistance may be obtained from the extensive 

 collection of biographies and literary histories in the Heading 

 Koom. How numerous these are will be seen by referring to 

 the Index of Subjects in the published " List of the Books 

 of Keference " drawn up for the use of readers by Mr. Bye.* 



In arranging the bibliographies in their cases, the subjects 

 have as far as possible been made to correspond in position 

 with those in the Library of Beference : thus the theological 

 bibliographies will be found opposite to Theology, and the 

 historical opposite to History. 



For press-mark the extra cases are distinguished by the 

 letters BB. — an abbreviation of the word bibliographies- — 

 in combination with the distinctive letters of the tables 

 against which they are placed: thus the press-mark BB. A, 

 shows that the work to which it refers will be found in 

 the bibliographical case standing at the end of the a table.
