Library means collection  of books and other informational materials   made  available to    people  for reading, study, or reference. The  word  library  comes   from liber,  the  Latin  word   for  “book”.   However,  a  library  is  in the  process   of identifing,   exploring  and  collection  of  data from  various sources.  Contemporary libraries  maintain collections  that  include  printed  materials  such as manuscripts, books, newspapers,  and  magazines,  but  also  art reproductions, films, sound and video recordings, maps, photographs, microfiches, CD-ROMs, computer software, online databases, and other media.
