# Euler's works after blindness

There are many sources which say that Euler produced, on average, one mathematical paper every week in the year $1775$. Some even say he produced almost half his total works despite the total blindness.

I can't seem to find much works after $1770$, on the page linked it says for the square root of -1 (1777) and Cauchy-Riemann equations in $1777$ does anyone have some references to Euler's works after he got blind?
