like the index, a table of contents needs to be crisp, clean, and easy for the reader to follow. these table of contents examples are extremely diverse, with various justifications. example 1 (top) shows a row of periods directing the reader to the page number; the others do not. examples 1 and 4 include the brief descriptions, or subheads, of each chapter. example 4 is the only one in which the page numbers are not aligned, which may be a little jumbled-looking for the reader. i like the use of space in example 5 (a cookbook). chapters and recipes are clearly organized, page numbers are aligned beautifully, and i like the use of page numbers and chapter name in the right margin. example 3 is a favorite as well. i like the chapter names and page numbers in the center, and i like that the chapter names are bold. it's pleasing to the eye.
