Ramanujan's total known/preserved output today is 37 published papers and these four notebooks; all of it is available on the site. The notebooks have been transcribed and published in several volumes with explanation (as mentioned above); those are the only thing not included on this site (and arguably, not "by" Ramanujan).
From the second paragraph:
> George Andrews and Bruce C. Berndt (2005, 2009, 2012, 2013, 2018) have published several books in which they give proofs for Ramanujan's formulas included in the notebook
And, frankly, I find it pretty upsetting that you seem to negate that equation.
