This study investigated information retrieval from hypertext on Intern
et's World Wide Web (WWW), Significant main and interaction effects we
re found for both link density (number of links per display) and displ
ay format (in paragraphs or lists) on search performance, Low link den
sities displayed in list format produced the best overall results, in
terms of search accuracy, search time, number of links explored, and s
earch task prioritization. Lowell densities affected user ability to p
rioritize search tasks:and produced more accurate searches, while list
displays positively affected all aspects of searching except task pri
oritization. The performance of novices and experts, in terms of their
previous experience browsing hypertext on the WWW, was compared. Expe
rts performed better, mostly because of their superior task prioritiza
tion.
