LIBRARY OF THE CAMBRIDGE ENTO- 

 MOLOGICAL CLUB. 



The librarian of the Cambridge Entomological 

 Club calls attention to the desirability of preserving 

 in the library of the Club as complete a series of 

 entomological publications as it is possible to collect. 

 It is especially desirable to preserve the transient 

 literature of the subject — separates, small pamphlets 

 and newspaper articles — and the librarian will be 

 pleased to receive single copies of the daily papers, 

 scientific journals, magazines, or agricultural papers, 

 which contain entomological articles. These papers 

 are preserved and catalogd, and, because they are 

 overlooked by large general libraries, are just the 

 kind of material that should be preserved in a special 

 entomological library. Any one who has sought for 

 some of the best of the agricultural journals of the 

 western states in libraries will appreciate any effort 

 made to preserve journals of this sort. 



Separates which are often thrown into the waste- 

 basket, as useless, as too small for preservation, as 

 duplications of parts of serials, or as valueless, are 

 respectfully solicited. The friends of the Club are 

 also asked to send a copy of newspapers in which 

 they have published articles or notes on entomologi- 

 cal subjects. If these notes are anonymous, the 

 author's name will be acceptible information. 



The accessions to the library of the Club had 

 reached the number of 1643 at the end of last year 

 (1887). 



Direct all papers for the library to 



Cambridge Entomological Club, 



Cambridge, Mass .
