 Annual iurvey of embryological literature 



INTRODUCTION. 



From several sides we received the request whether the Hubrecht Labo- 

 ratory should be willing to publish an annual survey of the ,, complete" 

 embryological literature of the preceding year. After we had gathered infor- 

 mation concerning the desirability and about the possibility of getting enough 

 cooperation for realizing this project, we can announce that the Hubrecht 

 Laboratory is willing to organise such a service in the near future. 



We therefore propose to split the G.E.I.S. into two sections — one giving 

 a survey of the current scientific work in the year in question and the other 

 giving the literature published in the preceding year. 



In order to avoid confusion, we draw your attention to the different aims 

 of both sections, a) The survey of the current scientific work will simplify 

 correspondence among workers on related subjects and will stimu- 

 late international cooperation and team work, b) The 

 survey of the literature published in the preceding year will make the 

 extensive modern literature more easily accessible 

 to every embryologist. 



We propose the following organisation. 



Every embryologist will be asked to send to the Hubrecht Laboratory all 

 his/her publications dealing with embryology in its widest sense, so that we 

 can compose a general list from our own collection. 

 In this manner we need only the promise of every embryologist to send us 

 all his/her publications. This form of organisation includes a great saving of 

 time and work to every collaborator and guarantees, moreover, that all publi- 

 cations listed in the G.E.I.S. are present and available at the 

 Hubrecht Laboratory. In this way, the central library will be of direct use 

 to every embryologist. Once a year we will send a request to every embryo- 

 logist for the latest literature. This year this request will be included in this 

 issue of the G.E.I.S. 



As at the present moment the central embryological library has not yet 

 reached such a degree of completeness that it can already give a m o r e or 

 less complete survey of all embryological literature published over 

 the whole world, and Mr P. D. Nieuwkoop will probably leave the laboratory 

 for one year, we believe that it will be better to start such a service not 

 before next year. 



W e, however, ask every embryologist to send all 

 his/her recent and older publications so that we will be 

 able to publish a more or less complete survey of the embryological literature 

 in the course of the year 1952.
