Business-English dictionary you'd recommend ...

[nat.wroclaw]

Hi,

November - the month of the double tax is a good time for work-aid equipment.
Which Business English dictionary would you recommend?

I teach business English but having no business degree sometimes need to look
up some more problematic vocabulary or be able to learn simply what certain
issues are.

I've been using google so far, but I think I can pump up my paper-library too :))

Any recommendations?

Thank you

Natalia
