As our profession grows larger and more diverse, as its opportunities increase, the proper conduct of our national meetings becomes a matter of legitimate concern. This booklet brings together explanations and regulations developed over the years. We urge that group officers and readers of papers—and any member who thinks that he may ever read a paper, lead a discussion, or organize a program at the Annual Meeting—read all of the booklet carefully so that they may see how each activity contributes to the success of the whole meeting, which now numbers more than 12,000 in attendance, more than 100 different programs in three days, as many as 600 individual participants, and in 1967 begins to occupy the full facilities of two separate, major hotels.
