[ 519130 ] = Internet publishing and broadcasting and web search portals — Catalog of collections publishers, exclusively on Internet
Today, there are online resources available. Either with free registration (possibly for the purpose of gaining sales leads) or a paid subscription (for the same purpose), individuals and companies can learn all that is available. In a single catalog, there may be tens of thousands of entries — companies, products, and services available to all customers.
Some of these catalogs are filled with every home network (home automation) product in many categories . This may sound like a great idea, but the volume of information may add frustration to the search for best products. Research for best products may begin with such catalogs; it clearly does not end with them.
