There are many good books available on-line (which may help to solve problems of availability).
Many of the "classics" dating from antiquity to modern times are available at
Project Gutenberg
More recent offerings might be found at

Mortimer Adler has compiled a list of these "classics" which some US schools (
List of schools) use as the basis of their liberal arts education.
While most of the books on this list are written by authors in western cultures (and are representative of the foundational philosophies of Western culture), many are of Asian and other Eastern cultural origin.
