摘要：Please send in immediately to Headquarters, 4580 Scott Ave., St. Louis, Mo., any changes in address, name or personnel of your library. The key list will be revised at an early date. The key list is the property of your library. Please see that it is kept in a prominent place so that it will be available at all times. Short lists of fragmentary "wants" will be listed in the Exchange lists as''usual, but there is no demand upon the members to look these up. The members whose wants have been filled have been very appreciative in the past, but the main purpose of the Exchange still continues as a clearing house for duplicates which must be moved.
