Auxiliary Table of Contents/doc
“ By adding nosummary, the export will contain both the links in the AuxTOC and the links in the original TOC. Without it, the export may only contain the contents of the AuxTOC. If some links are repeated on the root page's TOCs, they will be repeated on the exported file's TOC. If the same links are added elsewhere. For example, if the same links are presented on a subpage as well as on the main page, the entries from the subpage will be nested in the output file, so the subpage should be used and the main page table should use nosummary=y. ”
