Online indexes/databases are great places to search by subject/topic for books or for articles in scholarly journals, trade publications, popular magazines, newspapers, etc.
They often provide access to materials that are not normally available for free on the web.
Select databases that index information sources covering the field in which you are doing research.
For example, if you are researching the topic of "business ethics", you may want to start searching in a database that indexes business journals.
Check out the Bethel Libraries Web Page to see a list of possible online indexes/databases in which you could search.
