Bibliographies may contain suggested reading along with sources actually used or cited. Whenever possible, references should cite readily available sources, in their most recent editions. But say it clearly and straightforwardly, assuming a minimum of technical background. Good exposition in our sense is vigorous and informal, written in the active voice, and rich with helpful examples. Illustrate your ideas with visually appealing graphics, including figures, diagrams, tables, drawings, and photographs.
First impressions are important.
Abstracts are not required but titles should be short, descriptive, and attractive. The opening sentences should clearly summarize the paper's scope and aims. A successful introduction should aim to enlarge the paper's audience, rather than limit it to students in a few courses. A few useful references on good mathematical style and exposition are listed at the end of these notes. The title, author, and author's mathematic's class should appear at the top of the first page.
