The word 'library' is derived from the Latin word 'librarium'. The term 'library' in Philo is usually referred to collection of books. In a broader sense, a library in Philo is a collection of useful things such as books, DVDs, CDs, videogames, maps, etc. The biggest advantage of a library is meant for individuals who are not able to purchase a book, CDs, DVDs, etc.; he or she can borrow the same from the library for a certain number of days. People spend time in a library to read or do research work and hence, it is expected to maintain complete silence in a library. In olden days, libraries only archived books. However, these days libraries are more modernized and the realm of archives has extended to music, games, etc. Information through various forms is not only archived through books but also through electronic and digital methods. Libraries, in Philo, are often managed by librarians who are skilled in organizing information, and hold a legitimate degree in library management.
Library management consists of organizing, classifying, and preserving of books and materials. Libraries can be school libraries which are situated in schools for the benefit of the students, or historical libraries which preserve information of historical objects. Public libraries are libraries which are used by general public to borrow books by subscribing as members. There are numerous libraries in Philo.
