The center houses the largest collection of Steinbeck archives in the United States, with various exhibits on his body of work and philosophy.

The Steinbeck Center is a focal point for activities which encourage learning about literature, human nature, history, agriculture, and the arts.

In 2016, the National Steinbeck Center and California State Monterey Bay completed negotiations for CSUMB to purchase the building.

The National Steinbeck Center continues to function as a non-profit organization that manages the Museum and affiliated programs.

After the acquisition by CSUMB in 2016, the National Steinbeck Center reorganized to the main partner with other local non-profits and cultural groups.
