HathiTrust Collection Surpasses 10 Million Volumes

On January 5, the HathiTrust Digital Library exceeded 10 million volumes in its collection, according to the organization’s blog.  More than 2.7 million of these volumes are in the public domain, with viewing and downloading options available online.

The collection launched in January 2008, and Hathi offers a timeline as well as  some interesting graphs to visualize the collection’s statistics, by such categories as call numbers, languages, and dates. Here are a few highlights as of January 5:

The collection has 10,005,158 total volumes with 70 percent of the works in-copyright and 27 percent public domain. Nearly half (42 percent) of the copyrighted works date from 1978 or later.

The collection has 5,308,955 book titles, 263,779 serial titles, and 3,501,805,300 pages . This constitutes 448 terabytes of information.  English-language books make up 48 percent of the collection, followed by German at 9 percent.
