If you do any kind of research on foreign companies, it’s imperative to know how the companies are structured. Canadian businesses fall into one of four categories — sole proprietorship, partnership, corporation, or cooperative — and corporations usually carry the designation Inc., Corp., or Ltd.
For foreign companies, there’s an array of other designations and extensions. This page provides a list of these extensions and explains what the terms mean and where they are used. The list also helps narrow your search if you don’t know what country a company is based in.
I just came across a terrifically handy tool from Alacra called the Periodic Table of Business Research Databases for identifying the right database for business-related research. There are a vast number of databases available on the market, each with its own focus and content depth. This tool provides a nice, quick and dirty overview of most of these information sources, identifying them by the various categories of research (company profiles, credit and investment research, market research, news, etc.).
Unfortunately it is missing some key Canadian databases, such as Infomart and Newscan, but I’ll be bookmarking it.
