Like the print media, users can use the table of contents to move to the information of interest to them. As a Web publisher you need to ensure that the users have the option if appropriate. Alternatives to table of contents are site maps and indexes. Set an electronic bookmark for the page. Make sure you use descriptive titles so users can recognize the name in their bookmark listing.
Users can scroll through the current page.
Depending on organization and navigation of the Web pages, may or may not be able to easily see what else is available. Users can still write notes but cannot place them with the information.
