Open your word processing software and navigate to the References section. In Microsoft Word, it is located on the horizontal ribbon at the top of the page.
Select a style for your bibliography (APA, Chicago, MLA, and so on). In Microsoft Word, this can be done with the drop-down box next to the word "Style." Different styles are preferred by various academic disciplines, and should be listed on the syllabus of your course; if not, consult with your instructor.
Click "Insert Citation" and "Add New Source." A box labeled "Create Source" will appear.
Select the "Type of Source" drop-down box and choose from a wide variety of sources: books, articles, films, websites and so on. The "Bibliography Fields" will immediately adapt to reflect the information required for the bibliographic style you selected.
Enter in the required fields and click "OK." Repeat for all sources used in your paper.
Position the cursor to the end of your paper and click "Bibliography" on the References tab. Choose "Insert Bibliography," and your sources will automatically appear in alphabetical order.
