When you choose to search in Ebsco, it is common to "select all" databases for your search. BUT if you are looking for very specific items, it can be worthwhile to choose more deliberately. 

For example, if you are looking for company or brand information, choosing "Business Source Premier" only, will give you easier access to company and industry reports. 

Notice that in the list of databases, there are a lot of very specific collections. The eBook collection listed at the very top is only one collection of eBooks, so when you are search for books, it it better to select all databases. 

All of the databases include the cite button!
