PALÉOZOOLOGIE ET PALÉOPHYTOLOGIE 173 



Règles bibliographiques 



par M. F. -A. Bathkr. 



The following recommendations hâve been made by ihe Commit! ce of the 

 Britisch Association on Zoological Bibliography and Publication; and, by 

 resolution of the Gommittce of Section D (Zoology), I am desired to réquest 

 your favourable considération of them. 



Melhod of making Références to Previous Literature. - - The question is : 

 What is the best way in which the author of a paper can introdude referances 

 to the works which he quotes or otherwise alludes to ? No single method 

 suits ail cases. At the outset a distinction must de drawn between 1 wo classes 

 of papers : fir^t, brief articles, in which the références are corrcspondingly 

 few and rarely repeated ; secondly, longs articles or memoirs, in which the 

 références are correspondingly numerous and frequently repeated. 



In articles of the first class, références may quite easily be worked into the 

 text, and can be repeated by giving the cited autlor's name, with a distin- 

 guishing date when more than one of 1 is works has been mentioned. This is 

 more economical of time, space, and money than footnotes, and is far less 

 fruitful of error than the irrita ting ibid. and loc. cil., often used by writers 

 who apparently do not know what the contractions really mean. 



For memoirs of the second class, it is more convenient for both autho'' 

 and reader to hâve, either at the end or at the beginning of the memoir, a 

 « List of Works referred to » (often erroneously termed a « Bibliography », 

 even when lamentably lacking ail bibliographie détails). This should be 

 arranged with the names ot the authors in alphabetical order, and with the 

 papers under each author's name in chronological order. the date of publi- 

 cation (month as well as year, if necessary) precedeng the title of the paper. 

 In those rare cases when two or more papers by a single author from a single 

 year cannot be distinguished by the month, the letters a, b, &c., may be 

 added. Examples : 



Lambert, J., Etudes sur quelques Echinides de l'Infra-Lias. Auxerre, 

 Bull. Soc. Sci. Yonne. LUI, 3-57, pi I. Janv. 1900. 



The références in the text will give the name ot the author followed (or 

 preceded) by the date, with the addition of a précise page-number wheie 

 required. Examples : 



« Mesodiadema simplex Lambert (Janv. 1900, p. 31), Middle Lias ». 



The Committee would repeat two suggestions made in 1897. First, that 

 the title of a paper (or at least its opening words) should be quoted, as well 

 as the journal from which it is taken. Secondly, that références should lie 

 given in full (i.e. séries, volume, pages, date), so that an error in one may be 

 corrected by the help ot the others.
