Incorrect page roman numberal page numbering in TOC

Question

So I have both arabic and roman page numbering for a report I am writing. The arabic displays correctly with no issues but the roman numerals display only the last page number they are used on before the TOC.

To be more specific, the first page is not numbered as it is a title page, then from there they are numbered with roman numerals up to the TOC where the TOC only shows iv for all pages on the TOC even through they have been newpaged and have different page numbers displayed.

Answer 1

The \addcontentsline commands should go where the section starts, so that LaTeX is able to provide the correct page number. I'd omit \protect\numberline{} that would push the titles to the right.

Also, I'd define some page styles, rather than resetting the parameters in the body of the document. The styles are frontmatter for the abstract and the other unnumbered sections, toclof for the table of contents and list of figures, mainmatter for the document body.

Answer 2

Some comments and observations:

• Your document has several unnumbered section-level headers in the frontmatter. However, because the corresponding \addcontentsline instructions are inserted only later, i.e., after \tableofcontents, the page numbers shown in the ToC for the three unnumbered section headers cannot be correct. The obvious fix: Insert the \addcontentsline{toc}{section}{...} statements immediately after the \section* directives rather than after \tableofcontents.

• Your document contains too many (and, moreover, poorly placed) \pagenumbering instructions. Please fix that. And, do note that the argument of \pagenumbering should not be empty.

• \listoffigures does not take an argument.

• Even though the title page shouldn't show an explicit page number, it should still be numbered, so that the second page has page number ii rather than i. Use \thispagestyle{empty} immediately after \maketitle to suppress the display of the page number.

• Optional: Load the tocloft package to suppress the bold-facing of page numbers in the ToC.
