I'd like to produce a document comparing all of the different bb (blackboard bold) fonts available in LaTeX. symbols-a4.pdf gives is what I will assume is a comprehensive list:

enter image description here

The problem is that three different packages override the \mathbb command. I tried to 'save' each version as shown in the following MWE, but to no avail:


$\amsbb{N} \bboldbb{N}$

Using \def in place of \let doesn't work either. How can I use multiple versions of \mathbb at once? (And what is wrong with my MWE?)

You should look at the source file for the Comprehensive List (/usr/local/texlive/2012/texmf-dist/doc/latex/comprehensive/source/symbols.tex on TeX Live); look for \IfStyFileExists and you'll realize how many tricks the author did for loading all the fonts. – egreg Dec 15 '12 at 13:23
Depending on the number of usages, you could also consider including an image of the "foreign symbols" by compiling it in a separate standalone document. – Werner Feb 16 '13 at 1:32
