Where traditions and history used to be oral, the need to preserve the words of the Quran necessitated a method of preserving the words by some means other than orally. Mosques that were the center of everything in a Muslim society's day-to-day life became also libraries that stored and preserved all knowledge, from the Quran to books on religion, philosophy and science.

More than ever, the 21st Century library is the digital library. As of 2016, over 90% of public libraries have e-book collections, and over 25% circulate e-readers or tablets. Librarians are increasingly responsible for both physical and digital collections. A digital collection can include sources created and distributed digitally, to physical documents scanned and provided in a digital format.

Many might also feature Video and Audio recording studios, complete with advanced computers to help users edit their creations.
