PHOTO‐COPYING AND DUPLICATING PROCESSES

Let me first of all congratulate Aslib in bringing before its members these various photo‐copying and duplicating processes. Book reviews and advertising literature serve a most useful purpose by introducing the machines to our notice, and in keeping us aware of the progress made in this field. The capabilities of any machine or process can, however, only be fully appreciated by actual demonstration which enables us to compare their possibilities with our own requirements.
