How many photocopies of one work can be placed on reserve for one class?
The number of copies should be reasonable in light of the number of students enrolled (perhaps 1/4 to 1/3 the number of students in the class), the difficulty of the assignment, and the time the students have to complete the assignment. If the decision to place the copies on reserve is spontaneous, with too little time to get permission from the copyright owner, more copies may be placed on reserve than usual.
