Welcome to eval hell! Once you start using it, you never get rid of it.

for journal in A B all
do
  eval "echo \$\"\${${journal}_1999[@]}"\""
done

There might be a much better way to do it, but I never bother with associative or otherwise nested arrays in shell scripts. If you need such data structures, you might be better off with a scripting language that supports them natively.

Actually, bash has support for associative arrays after a fashion. Whether they can be useful to you is another question, it's not portable to other shells in any case.
