Clara,

What you said in your second paragraph below is essentially correct. Use "t"
only when you are supplying both a publication date (bracketed or otherwise)
and a copyright date. Use "s" when you supply a publication date alone, even
if that date is a probably date of publication based on the copyright date.

Subject: DtSt type when probable publication date the same as the copyright
date

Dear colleagues, I have seen inconsistent treatment on the issue: When the
264  1 publication date is supplied uncertainly with square bracket but the
same year with the real copyright date (probably based on the copyright date
in most cases), what DtSt should we use? "t" or "s"? I have found some are
using "t", some using "s".

I kind of remember that I once read a post about the issue. At the
beginning, it encouraged to use "s", but later the post master said that
getting some official response that since both copyright and publication
date is supplied, "t" should be used even they are the same. However, since
only publication date is required, it is fine by not supplying copyright
date. If not supplying copyright date, it's fine by just using "s".

What should be the right practice? Thanks.

Clara
