5. Fourth quarter, 1913 (October-December)

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

 Titles of papers are freely shortened, minor words ignored, common terms con- 

 veniently abbreviated or chemical symbols substituted ; surnames of collaborators 

 are connected by hyphens; most pitnctuation marks are omitted — all for the sake 

 of condensation. Heavy faced Roman numerals indicate volumes; heavy faced 

 Arabic numerals designate mmibers and dates of issue (slanting lines separate 

 numerals for months and days). Bibliographie items begin with em dashes. 

 When two or more papers by the same author occur together, they are duly num- 

 bered, and separated by semicolons, but follow the same em dash. Numerals 

 preceding italicized names of authors indicate sequence in the bibliography 

 {index numerals) ; numerals preceded by commas, at the ends of items, indicate 

 initial pages of the corresponding papers. 



Index (subjects). The numerals in the index (page 320) 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. 320). Abbreviations 

 of words 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. 



Journals included: Biochemische Zeitschrift (B.Z.), Zeitschrift für physi- 

 ologische Chemie (Z.p.C). Journal of Biological Chemistry (J.B.C.), Biochem- 

 ical Journal (BJ.), Biochemical Bulletin (B.B.). 



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

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

 in the bibliography contain any papers (during the given quarter) on a particular 

 subject, e. g., lipins, find the key word in its alphabetical place in the index and 

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

 (in this case 39, 84, 209, 435-43-9, 613-4-7-9). The abbreviated items thus iden- 

 tified give the names of authors and suggest the nature of the corresponding 

 papers (ten papers in the case selected for Illustration), and help the reader to 

 decide whether to examine the original publications. When the index gives a 

 negative answer to an inquiry, a large mass of literature is removed from further 

 consideration. During the intervals between publication of the indexes of Jour- 

 nals, Zentralblätter and year books, this running bibliography directs the reader 

 to most of the main tracks through current literature on the leading biochemical 

 subjects.
