Duke Universities Libraries Site
This is a great site to help you understand how to handle "in-text" citations and "works cited" entries. Please make sure that you choose the Modern Language Association (MLA) entry. This site shows students how to handle "works cited" entries for a variety of other styles: APA, Chicago, Turabian and CSE. Scroll down for web-site link.
Pay close attention to the guidelines given at the bottom of each entry for specific important information that you must gather for each of the different types of sources.
Note: I would recommend that you letter and not number each of your souces. I think it is easier to keep them separate. Then, when you tie a notecard to a source you can use a letter and a number in the upper, right hand corner to indicate "which" source your note cards came from. Also note that the second line (and all others after it) of this MLA Entry should be indented. I also find it important to list the ISBN number, call number or location in the bottom left corner if one needs to find the source again for reference.
