BB and IBB confusion

[MyDogSparty]

When reading statistics on websites like Baseball-Reference, MLB etc. are intentional walks included in the BB column or do you add the IBB column to the BB column to get total walks for a player?

BB (base-on-balls) is Total Walks.

IBB (intentional base-on-balls) is those walks which were intentional (and are already counted in BB)
