I am very fond of the fonts M.R.C. van Dongen used to typeset his book LaTeX and Friends. I believe it is the same as Hatcher uses for his books (for instance Algebraic Topology), and also the one in which the Princeton Mathematical Companion is written. It is called FF Nexus, and it costs 200$. Here's what FF Nexus looks like.

Is there a free alternative, that contains very similar fonts?

  • as Nexus is an almost identical, a bit more playful, twin of Scala (by the same designer), I suggest you have a look at Cabin, and this question: tex.stackexchange.com/questions/117925/scala-sans-font (of which I think your Q might be considered a duplicate). – Nils L Oct 7 '13 at 8:12
  • Is ‘the Princeton Mathematical Companion’ The Princeton Companion to Mathematics? My PDF copy says (on p. iv) “This book has been composed in LucidaBright”, and the Poppler pdffonts program agrees that it's Lucida Bright (apparently with a little Helvetica and Times Roman). – user570286 Nov 16 '20 at 2:27
