A good source of information for any industry, from the aerospace industry to the transportation industry, is an online industry portal. But how can you find the right portal? The easiest way would be to Google the name of your industry and see what comes up. Another way is to use a site like virtualpet.com, which collects links to various industry portals. So if you're looking to do transportation industry research, for example, you can get instant access to all the leading web sites covering that industry.
