Such libraries grow out of such persons taste for knowledge and, sometimes, for fashion. There are, of course, small scale private libraries owned by solvent lawyers, educationists and persons of literary taste. But such libraries contain books on some particular subject or subjects chosen according to the taste and interest of their owners. Public library A public library is one which is open to the public. In order to cater to the taste and interest of all classes of people, a public library has to contain books on different subjects and varieties.
Such libraries may be seen in large numbers in every country. Most of these libraries are managed or subsidized by their states. The British Museum library of London and the Central library of Moscow are instances of public libraries. Again, many such libraries have been set up in England and America by philanthropic people like Mr. Carnegie, the American millionaire. Institutional library An institutional library is one which belongs to an institution such as a university, a college, a school, a chamber of commerce, a club or a governmental department.
Such a library is open to the members of the institution concerned and, therefore, generally contains hooks which are needed by them most. Importance of library As acquisition of knowledge depends mostly on reading, man has to read as necessarily as he has to eat. It adds to what he has already learnt and makes him strong and fit for rude battle of life. But for financial difficulties most of the persons who are keen on reading cannot purchase the books they need to read. Hence arises the importance of libraries.
Had there been no libraries, both public and institutional, such persons would have been deprived of their reading. The teachers and the students, in like manner, would be badly affected if their institutions had no libraries of their own. Conclusion Libraries attract people to read and thus create the habit of reading and- stimulate the thirst for more and more knowledge. But for the libraries, there would be no authors, no poets, and no thinkers. The libraries thus help in the advancement of learning and expansion of knowledge.
The library has another very important use. No research work is possible without a well equipped library containing valuable books of all ages, rare manuscripts and old records. A library of this type is thus of incalculable help in throwing light on unearthed subjects. Time passes in an unbroken continuity as does the water of the river. The books of the libraries are a record of this continuity. They thus enable us to know how human society has developed in thought and action step by step.
