The word "Library" has been derived from the Latin word "Liber" which means a book.' The word used in many other countries to signify a collection of books, publically or privately, is derived from a Latinized Greek word 'Bibliotheca' hence bibliotheque in French, biblioteca in Italian and Spanish, bibliotek in German, biblioteka in Russian and Toshosentsu in Japanese. The library is therefore, a place where books are kept. According to S.R. Ranganathan "a library is a public institution or establishment charged with the care of a collection of books and the duty of making them accessible to those who require the use of them." According to the New Encyclopedia Britannica which defines "Library is a collection of books used or reading or study, or the building or room in which such a collection is kept.” In this review paper we are going to see the present libraries functions and their environmental elements too.
