The Junior Members Round Table (now the New Members Round Table) began meeting as an informal group at the conference in New Haven, Conn.

"(1).  Its primary purpose was to organize social meetings and to hold a Round Table devoted to issues of particular interest to members of the ALA who were under thirty years of age (2).  In 1933 the membership age limit was raised to 35 (3).  The Junior Members Round Table continued to meet informally until 1941, when a constitution was introduced and approved with a few minor changes, and by-laws were proposed (4).  In 1942 several amendments to the constitution were made, and the by-laws, slightly modified from the 1941 version, were adopted."
