"Lalande, in his Bibliographie Astronomique, wrote from his own knowledge the title of the second edition of the work of Regiomontanus on Triangles, Basle, folio, 1561. He knew that the first edition was published about thirty years before, and so he set it down with the same title-page as the second, including the announcement of the table of Sines, Basle, 1536. Now, as it happened, it was published at Nuremberg in 1533, and there was no table of Sines in it. The consequence is that Apian and Copernicus are deprived of their respective credits, as being very early (the former the earliest) publishers of Sines to a decimal radius. No one can know how far an incorrect description of a book may produce historical falsehood; but there are few writers who have the courage to say exactly how much they know, and how much they presume."[6]
Before concluding this Introduction it may be well to say something about a few catalogues that have been issued in the different styles. One of the best classified catalogues ever published in England is that of the London Institution, which was first printed in 1835, and completed in 1852.[7] This has indexes of subjects, and of authors and books. The catalogue is very useful as a bibliography; and as the library was well selected, the reading of its pages is very instructive; but what shows the general uselessness of a classified catalogue for the work of a library is that in actual practice an alphabetical finding index has been in more constant use than the fuller catalogue.
Of an alphabetical catalogue of subjects an example may be found in that of the Library of the Board of Trade, which was published in 1866. Here the authors are relegated to an index, and all the titles are arranged under the main subject. This may be convenient under some circumstances, but it is not satisfactory for general use. The idea of the scheme was due to the late Mr. W. M. Bucknall, then librarian to the Board of Trade; but the catalogue itself was made by the author of this book. The system adopted was to use the subject-word of the title as a heading; but an exception was made in the case of foreign words which were translated. For instance, there is a heading of Wool. Under this first come all the English works; then the French works under sub-headings of Laine, Laines, and Lainière; then German under Schafwollhandel and Wollmarkt. From these foreign words in the alphabet there are references to Wool. There is, however, no more classification than is absolutely necessary; and it may be said that if all the books had been anonymous the scheme would have been an admirable one.
The Dictionary Catalogue mostly flourishes in America; but a very satisfactory specimen of the class was prepared by Mr. D. O'Donovan, Parliamentary Librarian, Queensland. It is entitled, Analytical and Classified Catalogue of the Library of the Parliament of Queensland (Brisbane: 1883. 4to). The books are entered under author and subject with full cross-references, and all the entries are arranged in one alphabet. There are abstracts of the contents of certain of the books, and references to articles in reviews. In the preface Mr. O'Donovan writes:—
"I have made a catalogue of authors, and index of titles, and an index of subjects, a partial index of forms, and having thrown the whole together into an alphabetical series, the work may be referred to as an ordinary dictionary."
Of the usefulness of the Dictionary Catalogue there cannot be two opinions, but the chief objection is that it is a waste of labour to do for many libraries what if done once in the form of a bibliography would serve for all.
A most important example of this class of catalogue is the Index-Catalogue of the Library of the Surgeon-General's Office, United States Army, of which nine large volumes have been issued. This owes its existence to Dr. J. S. Billings, and the publication was commenced in 1880. An enthusiastic friend is inclined to describe it as the best of published catalogues.
Authors' catalogues are the most common, and it would be invidious to point out any one in particular for special commendation.
