SELECTION TOOLS: NON-PRINT MATERIALS
The production and distribution of non-print materials, is a recent development and therefore not as well organised as in the ease of print materials, particularly from the point of issuing selection aids. The major types - microforms, audio-visuals and machine readable form are produced and distributed by the Unites States and countries like India have to import them. Another constraint is that these materials can be used only with special equipment. However, despite these constraints, Indian libraries cannot ignore these materials. Naturally selection of such materials will have to be done very carefully.
