In addition to the general operation departments for handling deposits, collecting items, and making loans, a bank also conducts a service department consisting of a number of internal and external divisions. The internal, or house, service divisions are auxiliary aids in the efficient administration of the bank, and their number will vary with the size of the bank. A large institution may operate the following divisions: (1) employment (interviews and engages new employees),

(2) medical (examines applicants for positions in the bank and gives medical attention to employees),

(3) educational (directs courses for special training in banking practice or for general studies in language or current economic events), (4) welfare (conducts recreation activities for employees), (5) library (maintains a circulating and reference library), (6) purchasing (buys supplies and distributes them thoroughout the bank), (7) stenographic (performs addressograph, multi-graph, and typing work). For the benefit of customers a bank may conduct external service departments as the following: (1) industrial (gives advice on problems of industrial management such as cost systems, purchasing, production, and sales methods, insurance taxation, and advertising); (2) foreign trade (furnishes economic and statistical information on foreign market conditions, shipping methods, and tariffs); (3) publicity (issues news letters on general financial conditions, pamphlets on special subjects, such as trade opportunities or investments, booklets on facilities offered by the bank, and press notices); (4) trading (executes orders to buy and sell securities on the market); (5) investments (recommends securities for investment); (6) taxation (computes state and federal taxes on incomes, excess profits, issues of bonds, and transfers of stocks).
