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 $Z\alpha$, where $\alpha$ is the fine structure constant. Theoretical errors due to various effects are critically examined and estimated.
