To the American Subscribers of the Concilium Bibliographicum 



(Zurich). 



The difficulties created by the war and after-war conditions and by 

 the death of Director Dr. H. H. Field have interrupted, from 1917 

 until recently, the sending out of bibliographic cards and of the 

 Bibliographia Zoologica. During this time, however, work has con- 

 tinued, although in restricted degree, on preparing references, and Vol. 

 30 of the Bibliographia Zoologica and certain cards have recently been 

 sent out to subscribers. 



The difficulties of the Concilium Bibliographicum caused by the war, 

 the uncertainties of exchange since the war and, finally, by the death 

 of Dr. Field have been so great as to threaten seriously the contin- 

 uance of its existence. But arrangements are now in process of accom- 

 plishment by which the continued existence of the Concilium is assurc-d 

 and the maintenance and even gradual expansion of its bibliographic 

 service provided for. These arrangements have been made possible by 

 a co-operation of the Swiss Society of Natural Sciences, the National 

 Research Council (Washington) and the Rockefeller Foundation (New 

 York), by which all current obligations of the Concilium are paid, a 

 certain sum is given to Mrs. Field in partial recognition of hitherto 

 unpaid services of Dr. Field, and financial provision is made for assist- 

 ance in meeting the current expenses of the Concilium for five years. 



A provisional managing committee composed of representatives of 

 the Swiss Society of Natural Sciences and of the National Research 

 Council will assume the present control of the Concilium, with Prof. 

 Dr. J. Strohl of the Zoological Institute of the University of Zurich 

 as Director. Full details of the new arrangements for the reorgani- 

 zation of the Concilium and proposed plans for a possible extension of 

 its work will be published as soon as the arrangements are formally 

 and legally made. 



In the meantime the making of the references and the preparation 

 and printing of the bibliographic cards will be vigorously pushed and 

 subscribers may be confident that they will again begin to receive cards 

 regularly, and that references to papers which appeared during the 

 war and in the first years after it as well as references to papers in 

 current periodicals will be sent them. An energetic campaign for the 

 confirmation of old and for obtaining new subscriptions will be begun 

 at once. The campaign for American subscriptions will be undertaken 

 by the National Research Council which will represent the interests of 

 the Concilium in America. The campaign in Europe will be made by 

 correspondence from Zurich and by personal visits to various countrio 

 by the Director of the Concilium. Special requests for information 

 concerning the Concilium may be made by American subscribers 

 directly to the National Research Council (Washington). DR. JEAN 

 STROHL, Director of the Concilium Bibliographicum. DR. K. 

 HESCHELER, Chairman, Committee on Concilium Bibliographicum, Swiss 

 Society of Natural Sciences. DR. VERNON KELLOGG, Chairman, Com- 

 mittee on Concilium Bibliographicum, National Krsr.irrh Council.
