A good library is an ocean of information, whose boundaries continue to extend with the endless contribution of the numerous streams of knowledge. Thus, it has a peculiar fascination for scholars, and all those whose thirst for knowledge is instable.

The usefulness of libraries in the spread of knowledge has been proved through the years. The field of knowledge is so extensive and life is so brief that even the most avid reader can never expect to absorb it all. Those who have a love for knowledge, therefore, try to master only a small fraction of it. Even this requires reading of hundreds of books, cheap and expensive, new and old. But few people are able to buy all the books on the subject in which they wish to attain proficiency. It is therefore necessary for them to visit a good library, where they can read a great variety of books on the subject they love. Besides, many old and valuable books on certain subjects are found only in a good library. Even the original manuscript of an author, who died several years ago, can be found in it, sometimes.

Today, men everywhere have discovered the benefits of learning. More and more books are being written to extend human knowledge and experience. Governments and individuals throughout the world are, therefore, opening more and more libraries to enable people to read as many books as possible. Libraries have been opened even in the remotest regions of the earth, so that people who are unable to buy books from the towns can still gain access to the various sources of knowledge. Mobile libraries serve the people in various parts of the Earth.

The importance of libraries, however, is felt most acutely by students in schools and universities, where most students are engaged in deep studies. The number of books that a student has to study, especially at a university, is so large that unless he comes from a rich family, he can hardly buy them all. Besides, many of the books may not be available in the book-shops within his reach. It is therefore to his advantage to visit a good library.

Some people even have then own private libraries in which they spend their leisure, reading the books that they have collected over the years and drive great intellectual benefit and pleasure.

In short, libraries have contributed so much to the extension of knowledge that they have become almost indispensable to all literate men.
