I would like to know what font this is or one very similar to it. Thanks!

Bentham  Suggested by TheBohoChick 

The font is embedded as "TiffanyRegular", but its name in the file is "Sterling Text". So... where is the truth ?

Yes, I found that. This is in the Roman family...I'm sure it's a dedicated font designed for them. I would like to know of one that is similar, I've seen this kind of font before several times but I don't know the names of them. Google search is not helping!

This one has the same feel.

I think it might be Garamond, but it seems too thick to be. Not sure.

Thanks everybody! I found one that I like on Google Webfonts, actually a couple. Serif: Bentham and Sans Serif: Puritan. I wanted a font that could be clear at headline level and uneven at text level, and both of these do that.
