What is the font used in Hartshorne's Algebraic Geometry book for sheaves? I originaly thought it was \mathscr as $\mathscr F$ looks very much like the symbol for a sheaf F there. But that can not be, because $\mathscr O$ looks just so different from the symbol for the structure sheaf in the cited book. There it looks closer to $\mathcal O$, though it is not quite that either.

Welcome to TeX.SX! A tip: You can use backticks ``` to mark your inline code as I did in my edit. – Corentin Feb 24 '14 at 18:12

Looks like Ralph Smith's Formal Script to me. – Paul Gessler Feb 24 '14 at 18:14

Btw, as Corentin already said: Welcome to TeX.SX! – Paul Gessler Feb 24 '14 at 18:24

Perhaps I was not clear enough: I am not looking for a generic way to identify a font (which is what the suggested link provides); I am really asking how to reproduce in LaTeX the specific font used for sheaves in Hartshorne. I do thus not believe my question is answered in the refered link. – user46792 Feb 24 '14 at 20:43

1I found the following post http://tex.stackexchange.com/questions/37519/different-mathcal-o which is about trying to find O in that specific font, where the issue does not seem to be resolved. – user46792 Feb 24 '14 at 21:04

@user46792: the issue is resolved, as the font has been identified in the comments of the question you refer to. As far as I know it has never been digitalized, so you won't find it exactly. – Philippe Goutet Feb 25 '14 at 07:50
