Lamb shift of $n = 1$ and $n = 2$ states of hydrogenlike atoms, $1 \le Z \le 110$

Theoretical energy levels of the $n = 1$ and $n = 2$ states of hydrogenlike atoms with the nuclear charge numbers $1 \le Z \le 110$ are tabulated. The tabulation is based on ab initio quantum electrodynamical calculations performed to all orders in the nuclear binding strength parameter $Zα$, where $α$ is the fine structure constant. Theoretical errors due to various effects are critically examined and estimated.
