X. PREFACE. 



I 1. Works published under initials are entered under the full name of the author, in 

 nil cases where the name has been discovered. 



III. \\ '.irks published by Popes are catalogued under the ecclesiastical name of the 

 author, with a cross-reference from the family name, when it has been ascertained. 



IV. Works by Archbishops and Bishops are entered under the family name, with a 

 cross-reference from the ecclesiastical title. 



V. Works of NobK'inm are catalogued under the family name, with a cross-reference 

 from the civil title. 



VI. Publications issued by Scientific and Learned societies are entered under the

I 1 1. Documents issued by Ecclesiastical bodies are entered under the designation 

 assumed by such bodies. 



VIII. Translations are catalogued under the names of the authors of the original 

 works. 



IX. Biographies are entered under the subject ; without a cross-reference from the

X. Acts of Parliament connected with any particular country are entered under the 

 name of the country ; while those passed in any particular reign are entered under the
