Currently I am not aware of a way to have an author's affiliation presented in the table of contents (TOC). However, when you click on the title of any article to view the abstract page, the author's affiliation appears in the side bar if you have that block enable to appear. This is configured in Step 5: The Look in the Setup section of the Journal Management Pages when logged in as a Journal Manager. If you select the Author Biography Block to appear in either the right or left side bar, the authors' affiliation(s) will appear when viewing the Abstract page for any article. If you'd like to suggest that OJS develop an option to present the author affiliation in the TOC in a future version of OJS, please submit a development request to that specific discussion board.
