Books, bulletins, pamphlets or other publications which the 

 student desires to retain in his library should be indexed on cards 

 and the latter placed in the file under the proper subject headings. 

 The usual author and title cards may be made out, and kept in a 

 separate file from the subject index. Cards for specially impor- 

 tant subjects in books and bulletins may also be made out, but if 

 this cannot be done, write a short resume of the work, or give the 

 chapter heads on the cards. 



Useful clippings may be pasted on cards and placed directly in 

 the file, or they may be pasted on sheets of paper of uniform size 

 and filed in folders. A vertical letter file is the best way to file 

 unbound publications, notes and clippings which cannot be placed 

 on the library shelf. Each bulletin may be given a serial number 

 as it is indexed, and all the cards made out for it given the same 

 number. The bulletins may also be filed in the drawers under the 

 same subject heads as are used in the file. The Cornell system 

 of filing bulletins in card-board cases open at the back, may also 

 be recommended, but the vertical file case has the advantage of 

 being free from dust, and the publications can be found more 

 quickly ; the greatest advantage, however, lies in the fact that the 

 bulletins, etc., can be so quickly returned to their exact place in 

 the file.
