Of the problems discussed, those posing the greatest obstacle for the full utilization of microform systems are: (1) the problem of identifying the material on microforms when it is associated with key words in computerized digitalized systems; (2) the problem of copyright in converting collections of material into microform stores; and (3) the problem of the payment to copyright holders for the reproduction of their works in on-demand, reproducing libraries, as well as the problem of payment to organizations which have made the investment of preparing microform masters of material in public domain and not subject to copyright. It is suggested that the establishment of a unique code for recorded knowledge and information would contribute to the solution of these problems and to overcoming two of the obstacles to the development of microform systems, e.g., identification and copyright. Since both information and copyright are international problems, they require an international solution. (Author/JB)
