The database contains basic information (basic properties, Galois orbit, field of values) for all Dirichlet characters of modulus less than $10^{20}$, with more detailed information available for those of modulus less than $10^5$.
L-functions are available for all characters of modulus up to 2800 (and some of higher modulus).
