I know it equals 0 on (0,1), 1/2 for y = 1 and 1 for y > 1 but I can't find a proof anywhere.
Perhaps someone recognises it and knows a page online or a book where I could find it?

Encapsulate the \(\LaTeX\) in backslash left braket and backslash right bracket. For inline use parentheses.
\[\frac{1}{2\pi i}\int_{ci\infty}^{c+i\infty}\frac{y^s}{s}ds\]
