In my worldview the Library is a place for knowledge and to search for knowledge. The physical location and the people that work here then caretake the knowledge and the various forms that knowledge takes. We become caretakers also of books. There are many other caretakers of knowledge and of books. Today's highlight comes from the World Digital Library Home.
Per the website:
The World Digital Library (WDL) makes available on the Internet, free of charge and in multilingual format, significant primary materials from countries and cultures around the world.
The principal objectives of the WDL are to:
•Promote international and intercultural understanding;
•Expand the volume and variety of cultural content on the Internet;
•Provide resources for educators, scholars, and general audiences;
•Build capacity in partner institutions to narrow the digital divide within and between countries.
It is still a small digital collection but amazing. Are you interested in "The Essentials of Arithmetic" by ʻĀmilī, Bahāʾ al-Dīn Muḥammad ibn Ḥusayn, 1547-1621? This is the place you can see the full text from Bibliotheca Alexandrina
