Definition
For the imaginary quadratic field $K=\mathbb{Q}(\sqrt{D})$ of fundamental discriminant $D<0$ and ring of integers $\mathcal{O}_K$, the Bianchi group here is $\Gamma=\mathrm{PSL}_2(\mathcal{O}_K)$. Its covolume is the hyperbolic volume $\mathrm{Vol}(\Gamma\backslash\mathbb{H}^3)$ for curvature $-1$ [3].
Parameters
$D$
—   fundamental discriminant of $K$ ($D<0$ a fundamental discriminant)
Formulas
(1)
$\mathrm{Vol}\bigl(\Gamma\backslash\mathbb{H}^3\bigr) = |D|^{3/2}\zeta_K(2)/(4\pi^2)$ is Humbert's formula [3] [1], where $\Gamma=\mathrm{PSL}_2(\mathcal{O}_K)$ and $\zeta_K$ is the Dedekind zeta function of $K$ [4].
(2)
Since $\zeta_K(s)=\zeta(s)L(s,\chi_D)$, where $\chi_D=\left(\frac{D}{\cdot}\right)$ is the Kronecker symbol and $L(s,\chi_D)$ is the Dirichlet $L$-function, the same volume is $|D|^{3/2}L(2,\chi_D)/24$.
(3)
$\mathrm{Vol}\bigl(\mathrm{PSL}_2(\mathcal{O}_K)\backslash\mathbb{H}^3\bigr) = |D|\sum_{a=1}^{|D|-1}\chi_D(a)\mathrm{Cl}_2(2\pi a/|D|)/24$, where $\mathrm{Cl}_2$ is the Clausen function.
Comments
(4)
The group $\mathrm{PSL}_2(\mathcal{O}_K)$ acts by orientation-preserving isometries on $\mathbb{H}^3$. The quotient by $\mathrm{SL}_2(\mathcal{O}_K)$ is the same orbifold, since $\{\pm I\}$ acts trivially.
(5)
The number of cusps is the class number of $K$ [3]; each entry comment gives the class number and the squarefree integer $d$ for which $K=\mathbb{Q}(\sqrt{-d})$.
(6)
For $D=-3$, the figure-eight knot group is a subgroup of index $12$ in $\mathrm{PSL}_2(\mathcal{O}_K)$ [2], so twelve times the $D=-3$ entry is the volume of the figure-eight knot complement. The $D=-4$ entry is Catalan's constant divided by $3$.

Data properties
Entries are of type: real number
How well the digits are known: proven
Table is complete: no (it holds every negative fundamental discriminant with $|D|\leq 1000$, matching the range of the quadratic Dedekind-zeta residue table)
How they were obtained:

Each value is a real ball at numberdb.bits(digits, losing=96) bits, computed from (2) by arb's Hurwitz zeta function. The generator writes $100$ digits.

Before the draft was filled, all $305$ rows were compared with (3), computed independently with arb's complex polylogarithm, and the class numbers in the comments were compared with PARI's qfbclassno. The special relations to the figure-eight knot complement volume and Catalan's constant were checked against the stored entries in the linked tables.
