Choice of an inner form for a library catalogue:
As can be seen from the foregoing discussions of the inner forms of a library catalogue, no particular inner form would effectively and equally satisfy all the requirements of library catalogue. Therefore, choice or the selection of an inner form for a library, depends both on the technical soundness of an inner form of a library catalogue as well as some important Management factors. Some of these management factors are: Types and kinds of users, and their document and information needs.
Library collection, both with reference to range of subjects and their scope and size of the collection.
Open or closed access.
Technical soundness of particular inner form.
Other environment factors.
With regard to the technical soundness of a catalogue, with reference to it's inner as outer form, no system is perfect to meet all the requirements equally well under all circum The decision, therefore, to design, develop and operate a library catalogue, has to be user-oriented. This is indeed the primary criterion!
In general, the general prescription is that a public library would do well with a dictionary catalogue, but a university, research or a special library would choose a classified catalogue to meet effectively the subject approach of specialists.
