What I have brought together here is a small, unashamedly UK biased selection from my own personal list of favourites. I have concentrated on free sites but mentioned a few worth-while priced services. Gateways Gateways are collections of links to other sites, usually covering a specific subject area or geographical region. My own company's collection of business sources on the Net. An Internet search tool and directory and a good starting point for any subject.
Many business people use the Net for share prices and company financials.
Free share prices are delayed by at least 20 minutes, but you can obtain real-time prices at relatively low subscription rates. The FT also gives 20 minute delayed stock prices for UK listed companies plus some brief financials. This is a priced service but you can be sure that if the company has a legal obligation to present accounts to Companies House, it will be in the ICC database. Virtually every major newspaper and magazine has a web site of some sort. Many of them are marketing sites and have only a couple of top stories from the current issue.
