reflection.....
The type of data base i perfer is the search Engines, meta-search or subject directories because of afew reasons
1)Even thought they have alot of information and might take awhile to filter though and find what you want they are easier to navigate and finding information is easier though might be longer
2)Also the variey of information in these search engines are more then that of the invisable web as they get information from the whole web while the invisable web gets information from the organization that set them up
