Online Marketing Successes
NorthernLight is another favorite search engine among researchers. It features a large index of the web, along with the ability to cluster documents by topic. Northern Light also has a set of "special collection" documents that are not readily accessible to search engine spiders. There are documents from thousands of sources, including newswires, magazines and databases. Searching these documents is free, but there is a charge of up to $4 to view them. There is no charge to view documents on the public web -- only for those within the special collection. Northern Light opened to general use in August 1997.
