20. What are the provisions of the school library law in regard to district-school libraries? =Value of Library Instruction.=—Such library instruction as has been described is of great help to teachers assigning work to pupils and of the greatest benefit to the pupils themselves. Without it, the librarian, teachers, and pupils are handicapped in their work and the library fails of its full usefulness. A knowledge of how to use a library will be of the greatest value to the student not only through his high school course, but even more so in college, if he goes that far, or in continuing his reading and self-culture through the means of the public library when he discontinues his academic career. To be able to use books effectively, to know where to find exact information when wanted, is a kind of knowledge that comes from familiarity with reference books and the use of books as sources. Such an acquaintance with books is of infinitely more value in later life than knowing a few text-books from cover to cover. The place in which to lay the foundation for this proper and intimate acquaintance with books as tools is in the school library and the period is that of the high school age. ----- Footnote 2: _School Review_, April. 1907, vol.

CHAPTER X. =SUGGESTED READINGS IN THE ENCYCLOPÆDIA BRITANNICA.= The new Encyclopædia Britannica will prove a rich mine for the diligent library assistant seeking information on topics connected with books and libraries. While the index volume suggests some of the topics in question, much of this suggestion is done by means of cross-references and it is worth while to call special attention to and briefly summarize the articles of interest to library workers. One of the first things worthy of notice is the fact that the articles are written by men who are recognized authorities in their various fields; such scholars as Sir E. Maunde Thompson, late chief librarian of the British Museum, Alfred W. Pollard and Cyril Davenport, also of the British Museum, H. R. Tedder, librarian of the Athenæum Club, and editor of “_The Library_” and J. Duff Brown, librarian of the Islington Public Libraries and author of the “Guide to librarianship” and other valued treatises on library economy.
