PREFACE. 



The Lloyd Library is devoted almost exclusively to Botany, 

 Materia Medica, and Pharmacy, with a section of Eclectic Medicine. 

 In recent years we have purchased a few books on Entomology and 

 general Natural History. In future we expect to gradually build up 

 the librar}^ in these lines. It contains at this time 46,895 volumes. 



The catalogue of our library has been compiled from all avail- 

 able sources, such as Jackson's "Guide to the Literature of Botany," 

 Pritzel's "Thesaurus Literature Botauicae," "Botanische Central- 

 blatt," "Index Catalogue of the Library of the Surgeon's General 

 Office," Catalogue of the Library of the British Museum, Catalogue 

 of the Library Royal Botanic Gardens, Kew, and book notices in 

 various journals. From this catalogue we have published bibli- 

 ographies of the sections of Floras, viz. : the botanical sections 

 K, L, M, N, O, P, Q, R, S, T, U, and V. We are now continuing 

 the publication of the remainder of the bibliography of Botany, 

 alphabetically by authors.* This will include the following sec- 

 tions :t 



A — Bibliography, History, Biography, Terminology, Encyclo- 

 paedias, Dictionaries, Directories, etc. 



B — Introductory Botany. 



C, D, and E — Physiological and Morphological. 



F — Phanerogams, General Descriptions. 



G^ — -Phanerogams, Monographs. 



H — Cryptogams. 



I — Palaeobotany, Plant Distribution, Miscellaneous. 



J — Economic Botany. 



W — Botanical Gardens, Museums, Parks. 



X — Voyages and Travels. 



Y — Agriculture and Horticulture. 



Z — Biology and Zoology. 



The books now in our library are indicated by the shelf num- 

 bers, printed in heavy-faced type, pamphlets by a heavy-faced star. 



* The first issue of the sei-ies by authors bore a misleading title. It should have read 

 "Bibliography relating to Botany exclusive of the Floras." For full statement of the di- 

 visions of the Botany section of the Lloyd Library see Bib. Cont., Vol. 2, no. 2. 



t Only a few titles relating to botany are given in the subjects included in the letters 

 X, Y, Z. These subjects will be covered more fully in later numbers.
