If you only use a search engine to find information, you may be missing a good resource in the form of a database. To make up for this gap, there are web sites devoted to listing databases available on the Internet. Go to the list of search engines, subject directories, and database collections. Just because it is there, doesn't mean it is necessarily accurate. Some are free and some are not.
Many companies are in the business of compiling information and charging for access to it.
The Santa Cruz Public Libraries purchases the rights to use several online databases. All of them are available to you for free when you use them in the Library. If you do not have a Santa Cruz Public Library card, contact your own local library and see what resources it makes available. The Internet has many great sources of information, but it is not the great repository of all knowledge. The information that you want may be available, but in some other format.
