Zoological Bibliographies 



In the March number of the NEWS, page 91, we published a 

 note headed "Save the Zoological Record !" Elsewhere in 

 the present issue is a statement concerning resumption of 

 publication by the Concilium Bibliographicum. Each of these 

 bibliographical agencies appears to have its partisans who see 

 nothing good in the other. Both have done good in the past

 advantages lacking in the other. 



For individuals working in a limited field the cards of the 

 Concilium are of very great assistance,* as they permit one to 

 associate each year's cards relating to any given subject, or 

 to the works of a given author, with similar cards of preced- 

 ing years, according to the recipient's preferences and mode 

 of work. This obviates the necessity of examining separate 

 volumes each devoted to the literature of but a single year f 

 Experience, too, has shown that the cards for limited groups 

 are distributed at a shorter interval after publication of the 

 literature than has been found practicable with the volumes of 

 the Record. 



For an institution including a number of investigators inter- 

 ested in different divisions of the animal kingdom and of 

 /.oology, the book form is doubtless the better, since the im-

 of this science and the quantity of papers published) demands 

 constant service to sort and interpolate the cards and few 

 establishments are able to supply this. The entire series of 

 cards for even one year necessarily occupies a much larger 

 space than a volume containing the same number of references. 

 This, too, is an important consideration. I Hit even when the
