Largest Libraries in the World by Holdings

About This Dataset

This chart ranks the largest libraries in the world by total number of items held, measured in millions. Holdings include books, manuscripts, maps, recordings and other catalogued items, not only printed books.

✨ AI Insight

The British Library holds the largest collection in the world at about 200 million items, narrowly ahead of the United States Library of Congress at 178 million. These two institutions sit clearly above the rest of the field. Turkey's Nation's Library and Russia's Russian State Library follow at 141.7 and 126.1 million, showing how national libraries dominate the upper ranks. A notable outlier is the New York Public Library at 55 million, the only entry that is a municipal rather than a national library. Below the top four the totals fall to a tighter band between roughly 42 and 58 million, spanning major national libraries in China, Japan, Germany and Denmark. The list underlines how a handful of national institutions preserve a vast share of the world's recorded knowledge.
