I'm trying to cite a "book" in APA format. I say "book" because I was not able to check out a hard copy from my library. Instead, I found a version that had been transcribed online. The website provides the following citation information:

RECORD: Darwin, C. R. 1868. The variation of animals and plants under domestication. London: John Murray. First edition, first issue. Volume 1.

REVISION HISTORY: Scanned by Kees Rookmaaker, transcribed (double key) by AEL Data, corrections by John van Wyhe 2.2006. Proofread and corrected by Sue Asscher 6.2008. RN6

Although this provides useful information, I'm not sure if I need to include all of it. Furthermore, I am unsure of how to consolidate it into one APA-approved citation for my reference list.
