However, the order of books in Alastair's Revelation Space series doesn't match up with I found on Goodreads
https://www.scifibooklove.com/book_series/revelation_space/ vs https://www.goodreads.com/series/56392-revelation-space
I recently started the series and went with Redemption Ark as book 2 (according to Goodreads) Hope I'm not missing too much going with the Goodreads ordering :/

When in doubt I'm heading over to the author's website...

His take on this is: " The reading order isn’t that critical, in my view, but it probably improves things to read REVELATION SPACE, REDEMPTION ARK and ABSOLUTION GAP in that sequence. THE PREFECT (AURORA RISING) and ELYSIUM FIRE may be read alone or jointly, but should best be read in the above order. CHASM CITY, as well as the collections DIAMOND DOGS, TURQUOISE DAYS and GALACTIC NORTH, can be read at any point."
