I very rarely use monuments for culture, never if I don't get myst as a starting tech. Why would you? So many reasons to not build them, but players seem to consistently do so anyway. So here's the numbers
Monument
Tech: myst 70
Cost: 30
Gain: 1
Library
Tech: writing 120
(reduced by both pottery and AH)
Cost: 90
Gain: 2
, +25%
, can run two scientists
So the difference in tech costs seem marginal, with either prereq tech the cost is effectively 100
, with both is 86
. Writing also gives OB for those AI that don't have it yet
As for building costs, a monument is far cheaper. Can't deny that. It's a 1 pop whip, which isn't great, but it's still far cheaper than a library.
So why do you still build monuments? Is it the 60
difference that makes you research an additional tech?
