  Quantum error correcting codes (QECC) is becoming an increasingly important
branch of coding theory. For classical block codes, a \href{codetables.de}
{comprehensive database of best known codes} exists which is available online
at \cite{codetables}. The same database contains data on best known quantum
codes as well, but only for the binary field. There has been an increased
interest in quantum codes over larger fields with many papers reporting such
codes in the literature. However, to the best of our knowledge, there is no
database of best known quantum codes for most fields. We established a new
database of QECC that includes codes over $\mathbb{F}_{q^2}$ for $q\leq 29$. We
also present several methods of constructing quantum codes from classical codes
based on the CSS construction. We have found dozens of new quantum codes that
improve the previously known parameters and also hundreds new quantum codes
that did not exist in the literature.
