Can anyone help me find a text I'm looking for? I recently started Alexander Rabinowitch's Prelude To Revolution, in which Rabinowitch mentions the April 4th meeting Lenin attended after his return to Petrograd the day before, at which Lenin first read his April Theses. The Theses themselves are pretty easy to get ahold of through a quick google search, but the meeting at which they were read doesn't seem to be online, or at least not where I've looked. The page on marxists.org for the Theses has the name of the meeting as the "All-Russia Conference of Soviets of Workers’ and Soldiers’ Deputies", though the earliest meeting I can find for this group is the "First Congress of Soviets of Workers' and Soldiers' Deputies", held in mid-June, whose meeting in June was actually called by the April conference. Does anyone know if there is any record of the April conference, or will I have to be content with just the Theses?

As well, there is another piece concerning the same period I'm trying to locate. On April 6th, there was held a conference by the Petersburg Committee of the Bolsheviks (at the time the R.S.D.L.P.(b)). Rabinowitch mentions that the shift in the party composition to a more radical line can be observed in the minutes of this conference. I'd like to find this document as well if anybody could point me to a source.
