Abstract: The resources of the library had been in clay tabled at the beginning of its concepts. Later, papyrus rolls were added to the library resources followed by leaves of some trees grown in the South Asian countriesaware that began using for writing (Palmyra leaves), and that palm leaf manuscripts were also added to library resources collection. With the advent of the papermaking, the character of library resources has been changed. Now, these library resources can be divided mainly into two parts. That is to say as printed and non-printed library resources. Books, journals, pamphlets, newspapers, leaflets, maps, ordinances, annual reports, gazettes, etc. are included under the printed library resources. E-books, e-data base, e-journal, scholar bank etc. are included under non-print library resources.
