Is there somewhere a database on Maass forms that includes eigenvalues, Taylor coefficients, etc...?
I am mainly interested in classical forms on $\Gamma(1)\backslash H$.

$\begingroup$ Thank you! This is good. But actually I would like to have more forms, even if less accurate. $\endgroup$– Alex GavrilovCommented Feb 19, 2014 at 12:55

$\begingroup$ I only see eigenvalues there. $\endgroup$– Alex GavrilovCommented Feb 19, 2014 at 14:09

As mentioned in the comments, the only big online database of Maass forms is that at LMFDB, with the data of 16599 forms so far.
In order to get the data on a more convenient format, you can go from the page of the Maass form (example) to the one of the associated L-function (example). There's a link from one page to the other at the right, "Related objects" -> "L-function". In the page of the L-function you can download a file with the coefficients and such (example), that's avaible in "Downloads" -> "Lcalcfile".
