indexed and easily utilized; and, secondly, to the fact that the 

 Compiler of the list has been limited in hei opportunities to the 

 Harvard Library, which, although fairly rich in this department, 

 has yet some grievous gaps. 



The Compiler and Editor have not aimed at producing more 

 than a " Trial List." By interleaving the little volume and insert- 

 ing in the appropriate place the omissions that will certainly be 

 found, and the additions which the next few years will bring, 

 scholars will find it possible, it is hoped, to gain some advantage 

 even from a list manifestly imperfect. The Editor need not 

 assure any one who is conversant with the subject that the work 

 has involved on the Compiler's part several months of assiduous 

 toil, and the exercise of much scholarly discrimination.
