The library can help preserve the materials in the archive and can access cultural materials by researching into the archival materials.Actually a database can be created for all the historical and cultural document and indexed with bibliographic details.

Libraries are much more than repositories of ancient or modern bibliographic material. They are a living organism, they are an integral part of the region or country in which they are located, but also of humanity.

As a repository, it has the function of preserving and caring, but as a living organism, it has the function of transmitting the information contained therein. In this context, it is also urgent to modernize and update the technological means so that they reinforce and support the technical staff who are in contact with the public and accompany them in their more or less complex research.

It is also important to mention the role of a space dedicated to conservation and restoration, with the aim of making it possible to restore the consultation of works in poor condition, simply returning them to the function for which they were produced, their reading.

Libraries, as repositories of printed books, are now more than ever essential to maintain. Unfortunately, many books and journals are now being published only in digital, electronic format. Those books and journals are not permanent. Who will take the trouble to update every digital book as technology changes? Will all those books exist in any form 200, or 400, years from now? Who will decide which books are worth forever maintaining? A single EMP (electromagnetic pulse) in the future, whether from the sun or from a nuclear war, can destroy all digital information and computers.

Libraries that scan printed material and then discard the original hard copies, to save space, are making a huge mistake. The scanned images of newspapers, journals, or books are only digital and never quite as clear as the original. Digital images and copies of books are very useful, of course, and we all rely on them. Digital versions also save wear and tear on original documents. But the original hard copies must be preserved, perhaps locked up and stored in a safe place for the future.

Cultural legacies/materials are physical artifacts and intangible attributes of a group or society. They are rated high above any work of arts or craft because when it is lost, the national identity and influence goes into extinction in the global community.

In preserving them, libraries creates a functional archive section where those materials are properly documented electronically with bibliographic details for easy retrieval. The cultural legacies can as well be converted from traditional to digital formats for longevity. In doing this, the physical structures of those cultural materials should be reinforced, be it material or artifacts. Also, libraries should engage in advocacies

via lectures, workshops and seminars which will be to disseminate information and cultural/historic events. By doing so, the legacies of a nation will be preserved.
