NOTE ON THE LITERATURE OF INVENTION AND DISCOVERY
Books on invention and discovery are mentioned here and there throughout this volume. The reader may wish further references, in which case he may find them at the public library nearest home. Within the past few years the public libraries of America have been laying stress on their educational departments, are becoming more and more a worthy complement to the public schools.
At the Carnegie Library, Pittsburg, the department of technology is directed by Mr. Harrison W. Craver, a graduate of a polytechnical institute, who has had experience as a practicing chemist. The collection keeps mainly to lines of local interest, and includes an ample array of trade journals. Indexes to articles in technical journals are maintained. On the shelves are files of patents of the leading nations of the world. Short lists of books on subjects of current interest are from time to time compiled and issued. Workers receive advice and personal assistance from scientifically trained men. Questions are answered by mail and telephone. Notes on books are appended to their titles on the catalogue cards, and in the monthly bulletin.
Mr. Craver’s aid extends to other public libraries, among them to that at Providence. Here the industrial department contains about 7600 volumes, chiefly devoted to the principal industries of the city,—textiles, electrical arts, machinery, and the arts of design, especially in jewelry. A room is at the service of draughtsmen: a dark closet is available for copyists who bring cameras. When a new book comes in the reader or the artist likely to want it is notified.
The Pratt Institute Free Library, Brooklyn, has an applied science reference room which receives 115 scientific, technical and trade journals. It has brought together a large collection of trade catalogues, duly classified, and a collection of cuts of machines and mechanical devices. The custodian makes it his business to visit the neighboring factories and workshops, so as to provide every publication likely to be of help. The use of this department increases steadily, with a marked effect on the proportion of scientific books taken from the general library for home reading.
Newark, a city of many and diverse manufactures, has a public library also of the first rank. Scientific books, as received, are brought to public attention through the press, and by means of the monthly bulletin mailed to any one on request. Short lists of selected works on particular branches of applied science are prepared for gratuitous distribution: in each book of a series the full list is pasted as a guide to extended reading. Readers are invited to ask for any book not in the library which they believe would be of service to them.
These are but a few examples of the work the public libraries are doing throughout the Union. At the headquarters of the American Library Association are issued manifold aids for readers and students: a list of them is given on a page following the index to this book. Let us hope that one of these days the Association may establish a bureau through which the literature of applied science, and all other worthy literature, may be passed upon by a staff of the best critics, for the behoof of all the people. Such a service would inure not only to the good of those who borrow books from public libraries, but would afford help to the men and women who buy books for libraries of their own.
