It has been estimated that the number of documents on the Web has been growing at the rate of four per second. That rate of increase will now increase exponentially to more than 240. A single decision by Lexis-Nexis to offer access via the Web means that its giant 2.5 TB (Terabyte) database, one which grows by nearly 240 documents per second, will dominate the Web. As Web access will be less expensive than access via the company's private telecommunications network, it is likely that 300,000 searches each day by the company's 1.3 million subscribers will shift to the Web. As most of the Lexis searchers are relatively skilled, the company is taking a chance that the users will be satisfied with response times on the Web. It is likely to fall far short of the six seconds achieved on the private network.
