Delgado Library has many on-line databases that can help you search for information on this topic. I would recommend Opposing Viewpoints as a place to start.
You can access this by clicking on the databases page link below and searching for Opposing Viewpoints under the list of titles.If you are not at City Park and click on a Database from the Database Page, it may ask you to log-in. If you are on campus, you will not need to log in, but from any other location you will need to log in with your user name and password. These would be the same username and password you use to log in to LOLA.
If you are using one of the computers in the labs at City Park you will not need to log in but from any other location you will need to log in with your user name (your LOLA #) and password (your birthdate formatted mmddyy).
