# Database or repository with values for the Hubbard potential U?

The Materials Project and other materials databases have a nice periodic table on their home page that allows you to search for compounds. For some materials, they give an empirical $$U$$ value used to model the bandstructure, and a reference to the paper. However, this information is available for a limited amount of materials.

Is there a databse or repository where one can find $$U$$ values obtained by experiment or determined ab-initio for metals across the periodic table?
