Whilst business in itself is not classed as a profession, though in its managerial aspects and specialized techniques it appears to be rapidly developing in that direction, the director can join a directors' organization, in the form of the Institute of Directors. The Institute aims to present a corporate view of its members' interests and, in this as well as other respects, it can be regarded as contributing to a process which will make its members into a profession. Its numbers and influence have certainly grown impressively in the years since the war, from a few hundred to over 36,000 (excluding members resident overseas) today.1 Apart from its library and information services it has also amassed, through its Medical Centre, a great deal of material concerning the medical and vocational records of its members.
