=Library Courses.=—One of the best library courses of this kind is that conducted by the librarian of the Detroit Central High School, where the work is graded to correspond with the regular grading of the English courses in that school. The librarian has a graded series of library questions which are among the best illustrations of this kind of work for high school courses available in print. We give specimens from the various series as follows: I. 1. Consult the indexes of poems by Holmes, and give the pages on which you find the following: (=a=) Poem beginning, “Listen, young heroes! Your country is calling.” (=b=) Poem entitled, “Dorothy Q.” 2. Between what streets in our city does 870 Lafayette Street come? II. 1. Look up the “Seven Wonders of the World” in two different books. Do not copy them. Name the books in which you found them. 2. In what work of literature does the “Old Man of the Sea” appear? In what reference book did you find it? III. 1. Find the allusion to “Field of the Cloth of Gold” in two different books. In what books did you find it? 2. Use the card catalogue and give a reference for the life of John Greenleaf Whittier. IV. 1. (=a=) Who was governor of Iowa in 1906? (=b=) Where was he born? 2. (=a=) Name two good recent encyclopædias, (=b=) Name two good older encyclopædias. V. 1. (=a=) What is the general index to Government publications? (=b=) How often is it published? 2. (=a=) What is the Congressional directory? (=b=) Examine it and name any one reference point which interested you. (=c=) What is the Congressional record? VI. Name good reference books under the following heads: (=a=) Classical dictionary. (=b=) Gazetteer of the world. (=c=) Atlas of the world. (=d=) Year-book for current history. There is an almost endless variety of questions which can be put to the students to bring out points in connection with reference books. They can be asked to name the various kinds of dictionaries in the library, to tell which is the latest issue, to look up the same word in each, and tell the differences noted in the treatment of the word in question. See whether they can define a gazetteer, a glossary, and a concordance. Ask them where they would go to find a picture of the human skeleton, or colored plates of coats of arms and flags of various nations. See whether the word copyright means anything to them.
