Here are differences that might be overlooked by writers making the transition from the seventh edition.
Books and Other Printed Works
The principles behind in-text citations in MLA style are unchanged. A few details have been added or clarified, though:
If you are already familiar with traditional MLA citation methods, continue to use them in a more simplified form. Since the eighth edition emphasizes the writer’s freedom to create references based on the expectations of the audience, consider what your readers need to know if they want to find your source.
Think of MLA style principles as flexible guides, rather than rules. Part of your responsibility as a writer is to evaluate your readers and decide what your particular audience needs to know about your sources.
