Often Universities or other academic organizations are responsible for creating these sites. They are different from directory type search engines, because the sites are limited to recommended choices. A new feature you may find while browsing on the Web is frames, also known as panes. When you open a framed document, you find that it displays two or more documents, each within its own pane. The frames around each document may be moveable and you may have scroll bars in each pane.
Printing framed documents can be tricky.
Remember to have your cursor on the page you wish to print. A form is a special interactive Web document. You'll find forms at the search engine sites. Some forms will ask for credit-card information. Be aware of Internet security.
