For double checking calculations I made I'd like to find a table of values of $L(-1,\chi_D)$ for small positive fundamental discriminats $D$. It there a table somewhere in the internet? Where?
With $\chi_D$ I mean the Dirichlet character associated to the fundamental discriminant $D$ and with $L(\cdot, \chi_D)$ the respective L-function. I know that you can compute those values using those formulars but for checking my own computations I'd like to have a reference whicdh simply states the result.
I don't understand your question, it is trivial to compute $L(-1,\chi_D)$, it reduces to the second derivative of $$-\frac12\sum_{m=1}^D \chi_D(m)\frac{x e^{-x m}}{e^{Dx}-1}$$ at $0$.
