Usage
As with shall and will, there are traditional rules about the use of should and would. These state that should is used with I and we (I said I should be late), while would is used with you, he, she, it, and they (you didn't say you would be late). However, these rules are no longer strictly followed and would is normally used instead of should in reported speech and conditional clauses: I said I would be late. In spoken and informal contexts the issue rarely arises, since the distinction is obscured by the use of the contracted forms I'd, we'd, etc.
For a discussion on the use of should of instead of should have, see usage at have.
Etymology
OE sceolde: past of shall.
