I have discovered that most industries have a sector catalogue. In
those catalogues most manufacturing companies are gathered together
and mostly these catalogues are published once a year. These are
catalogues are used to make it easier for importers or sellers to find
eachother easier and make trading easier.Most countries or
organisations publish their own sector catalogues and these catalogues
can be free of charge or very cheap.

I have been trying to find the companies which manufacture CASH
REGISTERS and ELECTRONIC SCALES (the ones that are used in groceries).


How can I get those sector catalogues from most major european and
asian countries that I can see lots and lots of companies
manufacturing CASH REGISTERS or ELECTRONIC SCALES?

Please help me out with that...
