_Biography._--Oettinger's _Bibliographie Biographique Universelle_ (1854) is a most useful work, although it is now unfortunately somewhat out of date.
_Book-keeping._--B.F. Foster's _Origin and Progress of Book-keeping_ (1852) contains an account of books published on this subject from 1543 to 1852.
_Botany._--Pritzel's _Thesaurus Literaturæ Botanicæ_ (1851, another edition 1872-77) is _the_ Bibliography of the subject, and this work is supplemented by Mr. Daydon Jackson's Index of Botany, published by the Index Society. Trimen's Botanical Bibliography of the British counties, London, 1874. 8vo.
_Chemistry._--R. Ruprecht, Bibliotheca Chemica et Pharmaceutica, 1858-70. _Göttingen_, 1872.
_Classics._--Dr. Edward Harwood published his "View of the various editions of the Greek and Roman Classics" in 1790. He was followed in 1802 by Thomas Frognall Dibdin, whose work was much enlarged, and reappeared in several editions; the fourth and best being published in 1827 (2 vols. 8vo.). J.W. Moss published his "Manual of Classical Bibliography" in 1825, 2 vols. 8vo. Henry G. Bohn's General Catalogue, Part II. Section I. 1850, contains a valuable list of Greek and Latin Classics. Engelmann's Bibliotheca Scriptorum Classicorum et Græcorum et Latinorum (1858) is an elaborate work on the subject, and Professor John E.B. Mayor's translation and adaptation of Dr. Hübner's Bibliographical Clue to Latin Literature will be found to be a very useful handbook.
_Dialects._--Mr. J. Russell Smith published, in 1839, a useful "Bibliographical List of the Works that have been published towards illustrating the Provincial Dialects of England" (24 pages). When the Rev. Professor Skeat started the English Dialect Society, he at once laid the foundation of an extensive Bibliographical List to include MSS. as well as printed works. This Bibliography is being published by the Society in parts.
_Dictionaries._--William Marsden printed privately, in 1796, a valuable "Catalogue of Dictionaries, Vocabularies, Grammars, and Alphabets."
_Dictionaries._--Trübner's Catalogue of Dictionaries and Grammars (1872, second edition 1882) is a very useful work. H.B. Wheatley's account of English Dictionaries was published in the Transactions of the Philological Society for 1865.
