Explanation of abbreviations, arrangement, notation, etc. Bibliography, 



Titles of papcrs are f reely shortened, minor words ignored, common terms con- 

 veniently abbreviated or chemical Symbols substituted ; surnames of collabora- 

 tors are connected by hyphens ; most punctuation marks are omitted — all for the 

 sake of condensation. Names of authors are printed in italics. Bibliographie 

 items are separated by em dashes, and are preceded by numerals indicating, for 

 index purposes, sequence in the bibliography. When two or more papers by 

 the same author occur together, they are regularly numbered and separated by 

 semicolons ; but follow one em dash. The numeral at the end of each item, 

 separated f rom the name of the author or authors by a comma and a small letter, 

 indicates initial page of the corresponding paper. The small letters between the 

 names of the authors and the page numerals, at the ends of the items, represent 

 specific volumes of the listed Journals, as indicated below: 



Biochemische Zeitschrift (BZ)^: a^65; b = 66; 0^=67; d = 68. 



Zeitschrift für physiologische Chemie (ZpC) : g = 92; h = 93. 



Journal of Biological Chemistry (JBC) : m = 18; n= 19; = 20, 



Biochemical Journal (BJ) : s= 8. 



Journal of the American Chemical Society (JACS) 3; ^ = 36; x = 37. 



Biochemical Bulletin (BB) : y = 3. 



Index (subjects). The numerals in the index (page 239) correspond with 

 the numbered items in the bibliography. Pages are not indicated. Numerals 

 held in groups by hyphens are piain abbreviations in accord with the indications 

 of the first numeral of each such series (see footnote, p. 239). Abbreviations 

 of w^ords in the index are similar to those in the bibliography. Each group of 

 index references is terminated by a semicolon ; commas mark off subdivisions 

 of a general index subject. Names of authors are not indexed. 



Practical use of the bibliography. The bibliography is useful from sev- 

 eral Standpoints. Thus, if it is desired to ascertain whether the Journals included 

 in the bibliography contain papers (during the indicated period) on a particular 

 subject, e. g., alcohol, find the key word in its alphabetic place in the index and 

 turn to the items in the bibliographic sequence indicated by the index numerals 

 [in this case 178, 180, 181, 183, 186, 205, 342, 351, 365]. The abbreviated items 

 thus identified give the names of authors and suggest the nature of the corre- 

 sponding papers (nine papers in the case selected for Illustration), and help the 

 reader to decide w^hether to examine the original publications. When the index 

 gives a negative answer to an inquiry, a large mass of literature in that connec- 

 tion is removed from further consideration. During the intervals between pub- 

 lication of the indexes of Journals, Zentralblättcr and year books, this running 

 bibliography directs the reader to the main tracks through most of the current 

 literature on the leading biochemical subjects.

3 Included in this bibliography for the first time. The section in the Journ. 

 Amer. Chem. Soc. regularly devoted to biological chemistry is steadily growing 

 in interest and importance.
