Users like the use of graphics and other ways to differentiate between pages. User's were asked if they prefer paper-based or hypertext documents. All the student users said that they preferred paper but three of the four library staff preferred hypertext documents. There is no need to wait for graphics to load. Browsing is easier in a paper document.
Computer screens cause eye strain.
It is easier to take in the scope of a paper document and be sure that you haven't missed out any information. Searching is quicker with hypertext than looking through an index. Printing from on-line documents is easy. Hypertext is easier to amend and update than paper. Hypertext is convenient for users who are using a PC all day.
