The International Personality Item Pool (IPIP) is a
public domain collection of items for use in
personality tests. It is managed by the
Oregon Research Institute.

and the
Big Five personality traits. IPIP provides journal citations to trace those inventories back to the publication as well as correlation tables between questions of the same factor and between results from different inventories for comparison.

Many broad-bandwidth personality inventories (e.g., MMPI, NEO-PI) are proprietary. As a result, researchers cannot freely deploy those instruments and, thus, cannot contribute to further instrument development.
