Is there a way to view a book's table of contents?
The HOLLIS Catalog entry for the book will include the table of contents, if it's available through standard cataloging. Including the table of contents is more likely with recent books. If there is a TOC included as part of the HOLLIS record, there should be a link to it in the blue/gray box at the far right of the scrreen; the TOC usually appears at the very bottom of the record; for example, this book.
If the TOC isn't included in the record, try the Google Books link, which sometimes provides it; if it's not there, try Amazon.com, which also sometimes provides it.
