Review of 'The robot novels.' on 'Goodreads'
5 stars
Especially in contrast against the Foundation books, these are a faster read, with stronger characters, and were just more fun.
You don't need to read them before the Foundation books generally, but I'd suggest reading them before Foundation & Earth and beyond. OTOH they'd also provide insight to Prelude to Foundation, IIRC.
I am enjoying finally reading about the famous Elijah Baley and R. Daneel Olivaw, and look forward to getting The Robots of Dawn from the library soon too.
