How do I enter angle brackets in bibtex?

Question

I want to put a title field in a bibtex citation that includes angle brackets:

@article{
  title= { <foo> }
}

but when it compiles I get upside down '!' and '?' instead. How to escape the angle bracket?

Answer 1

The main TeX font doesn't provide angle brackets—you have to use math symbols. Try

title = { $\langle$Foo$\rangle$ }

and be prepared for potential difficulties with alphabetization.
