Philosophers make imaginary laws for imaginary commonwealths, and their discourses are as the stars, which give little light because they are so high. – Francis Bacon
A book is a fragile creature, it suffers the wear of time, it fears rodents, the elements and clumsy hands. so the librarian protects the books not only against mankind but also against nature and devotes his life to this war with the forces of oblivion. – Umberto Eco
