II^TEODUCTIOI^ TO VOLUME Y 



VOLUME V. of the Bradley Bibliography contains the index of authors and titles enu- 

 merated in the preceding volumes and in the additions and corrections which appear in 

 this volume; it also contains the subject index to all the volumes. 



To confine the index to one volume it has been foimd necessary to shorten the titles as much as 

 possible; this has been done, however, without loss of clearness. The first words of every title are 

 always given in full and the omission of any words within the title as so given is indicated by dots. 

 Articles in serials, like the Botanical Magazine, the Botanical Register, Hooker's Icones and the Flore 

 des Serves, which are devoted entirely to the illustration and description of single species, have 

 been omitted, as they are not strictly independent articles; these may be found under the name 

 of the genus by consulting the subject index for its place in the systematic arrangement. Likewise 

 names of plants excerpted from books or articles and appearing in the systematic arrangement as 

 separate entries in brackets have been omitted. 



Anonymous publications are arranged alphabetically imder the first word of the title which is 

 not an article or preposition, but anonymous articles in serials or periodicals published with only 

 a botanical name as the title have been omitted, as they may be found under the name of the genus 

 by consulting the subject index for their place in the systematic arrangement. Anonymous articles 

 published without title in serials or periodicals and enumerated in the systematic arrangement with 

 a supplied title are also omitted, unless they have also been issued as separate publications. 



Serial publications of societies and corporate bodies will be found under the title of the publish- 

 ing body, and government publications of a serial nature under the name of the country. Other 

 publications, however, not of a serial nature, issued occasionally by societies, corporate bodies or 

 governments are arranged alphabetically under the title of the publication to insure uniform treat- 

 ment, as in many such publications taken from other bibliographies or sent by contributors to the 

 Bradley Bibliography the name of the publishing body was not correctly given or was omitted. 



This volume completes this work, the first volume of which was pubUshed in 191 L In it wUl be 

 found more than one hundred thousand entries of the titles of books and articles relating to trees 

 and other woody plants, their botanical characters, uses and cultivation. The enumeration is cer- 

 tainly not complete, for a bibliography of a subject so great can never be made complete, but it is 

 believed that in the Bradley Bibliography will be found the best key to the Uteratm-e of trees which 

 has been made. 



The Bradley Bibliography was begun and has been finished by Mr. AKred Rehder of the Ar- 

 boretum staff, who has devoted sixteen years of intelUgent, enthusiastic and uninterrupted labor 

 to this work.
