Note-taking, in other words, is a matter of brains and common sense: brains to see what is important, and sense to see that neatness and order are essential to true economy, the great virtue of notes.

With the best of intentions, then, you enter the library. Since each library is arranged on a somewhat individual scheme, and different collections have different materials, you will need to examine the individual library. A wise student will inquire at the desk for any pamphlet that may help to unriddle the special system. Librarians are benevolent people, do not wish to choke you, and are glad to answer any reasonable question. If your questions are formless, if you really do not know what you want, sit down on the steps and think it over until you do, and then enter boldly and politely ask for information. Don't, if you wish to learn about ship subsidies, for example, stroll in and inquire for "Some'n 'bout boats?" The complimentarily implied power of reading your mind is not especially welcome to even a librarian who is subject to vanity—and incidentally he may think that you are irresponsible. Any one who has been connected with a college library knows that the notorious questions such as "Have you Homer's Eyelid?" are not uncommon—and seldom bring desired results.

Since you have entered for information, summon all your resourcefulness to try every possibility before you agree that there is no help for you there. You can use the Card Catalogue, the Reference Books, the Indexes, Year-Books and Magazine Guides, and finally, if every other source fails, can lay your troubles before the librarian—but not until you have fought bravely. Too many students are faint-hearted: if they wish for information about, let us say, employers' liability, and do not at once find a package of information ready-wrapped, they sigh, and then smile, and then brightly inform the instructor, "The library hasn't a single word about that subject!" The Card Catalogue does not list employers' liability, let us say, and you do not know any authors who have written on the subject. Do not despair; look up insurance, workmen, accidents, social legislation, government help, and other such titles until your brain can think of nothing more. Only then resort to outside help.

The Card Catalogue will contain a card for each book in the library: if you know the title, look for it. If you know the author but not the title, look for the "author card." If you know neither author nor title, look for the general subject heading. For each book will usually have the three cards of subject, author, and title. If the subject is a broad one, such, for example, as Engineering, do not set yourself the task of looking through every card, but, if you wish for a treatise on the history of engineering, look for the word History, in the engineering cards, and then examine what books may be collected under that heading. If you find cross references, that is, a recommendation to "see" other individual cards, or other subject headings, do not overlook the chance to gain added information.

Most of us too often forget the encyclopædias. If the catalogue has been exhausted, then see what the encyclopædias may contain. Look in the volume that contains the index, first, for often a part of an article will tell you exactly what you wish, but the article as a whole will not be listed under the subject that you are seeking. The Encyclopædia Britannica, the New International, the Nelson's Loose Leaf will be of service on general topics. For agriculture consult Bailey's Encyclopædia. For religion see the Encyclopædia of Religion and Ethics (Scribner), the Jewish Encyclopædia, the New Schaff-Herzog Encyclopædia of Religious Knowledge (Funk and Wagnalls), the Catholic Encyclopædia (Robert Appleton).

For dictionaries you will find the Murray's New English Dictionary, often called the Oxford Dictionary, The Standard Dictionary, The Century, Webster's New International, Black's Law Dictionary and others.

Often you will wish to find contemporary, immediate material. The magazines are regularly catalogued in the Reader's Guide, month by month, with a combined quarterly and yearly and then occasional catalogue, with the articles listed under the subject and the title or author. Use your resourcefulness here, as you did in the card catalogue, and do not give up. Poole's Index will also help.

Many annuals are of value. The World Almanac has a bewildering mass of information, as does the Eagle Almanac for New York City and Long Island especially. The Canadian Annual Review, the Statesman's Year-Book, Heaton's Annual (Canadian), the New International Year Book, which is "a compendium of the world's progress for the year," the Annual Register (English), the Navy League Annual (English, but inclusive), and the American Year-Book, among others, will be of service. Often these books will give you the odd bit of information that you have hunted for in vain elsewhere. For engineering, the Engineering Index (monthly and collected) is useful.

For biography you will find Stephen's Dictionary of National Biography useful, and Lamb's Biographical Dictionary of the United States. Do not forget the Who's Who, the Who's Who in America, and the corresponding foreign books for brief information about current people of note.
