Using the Library. A reader must know how to use libraries. This means
he must be able to find books by means of the card catalogs. These are
arranged by both authors and subjects. If he knows the author of a
book or its title he can easily find the cards and have the book
handed to him. Very often he will seek information upon topics
entirely new to him. In this case he must look under the entry of the
topic for all the books bearing upon his. From the titles, the brief
descriptions, and (sometimes) the tables of contents upon the cards he
can select intelligently the books he needs. For instance, if he is
searching for arguments to support a new kind of city government he

_The Spirit of Youth and the City Streets. Old English Towns.
Municipal Administration. The Modern City and its Problems.
Personality of American Cities. Historic Towns of the

become skilful in using books. Many a trained speaker can run his eye
over titles, along tables of contents, scan the pages, and unerringly
pick the heart out of a volu
