Allow users to filter by:

Country / region
Type of university (public, private, research-intensive)
Library system vs. single building
Inclusion of off-site storage

Asia

University of Tokyo (Japan) – ~9 million volumes (incl. branch libraries)
Peking University (China) – ~8 million volumes
University of Delhi (India) – ~3 million volumes (but limited e-books)

6. How to Interpret “Better” Size Rankings

Better for research = large unique manuscript/special collections, not just volume count.
Better for students = high e-book access + 24/7 study spaces + interlibrary loan speed.
Better for preservation = climate-controlled storage, digitization rate.

For a pure volume ranking, Harvard, Oxford, Yale, Cambridge, Michigan are the top five globally. The list is ordered from largest to smallest
