Q. Ashland Oil, Inc. (B), Case

Are you asking how to write a business case study? If so, I've included some links below that describe how to write a case analysis, and how to analyze a case study. Their usefulness will depend on your assignment instructions. I have also included a link to our A-Z Database page, narrowed down to our Business databases. 

You can try your luck with Google Scholar, also linked below. Be aware you won't be able to access all of the results. Many will be behind a pay wall, becuase they are from subscription databases that COM Library doesn't subscribe to. If you search "ashland oil" (including the quotes), it will search that exact phrase. You can search for case studies at the same time by using the search phrase "ashland oil" AND case study. The capitalized and tells the database to search both ashland oil and case study at the same time. You can use the same technique for the databases listed above.l
