A good resource for your topic (social issues relating to abortion) would be Opposing Viewpoints in Context (http://libraries.state.ma.us/login?db=OVIC&locid=mlin_c_quinscc)--this will give you a choice of overview articles as well as articles that take positions on the issues. The articles come from reference books, magazines, scholarly journals, newspapers, and multimedia (radio/television news) so you have a wide range of sources to work from.
Call the Reference Desk (508-854-4366) if you are not finding what you want.
Thanks for your question.
