Newspapers:

Newspapers Of all the library materials, the newspaper is probably the most comprehensive, the easiest, to collect and the most vanishing type of a source. The newspapers reflect the conditions, events and forces of its time and the information contained in a newspaper is valuable. 

Since newspapers are printed on newsprint  (a type of paper) they disintegrate very fast. Therefore, they have to be conserved in an appropriate manner. Temporary bindings may result in some savings but such method are usually not satisfactory for long range conservation. Microfilming offers the best available solution  to the problem of conservation of newspapers. Newspapers can be bound in canvas covers or in an economy-binding consisting of stout boards covered with a paper like material with cloth of leather spines. Documents not considered as permanent to  the collection need not be bound even if their initial  use is heavy enough to warrant it. Some libraries prefer to acquire multiple copies to satisfy heavy initial  demand and bind only  one copy for the occasional request later. To this category belong current fiction and textbooks which are frequently revised.
