eblip-29285	Warren, Ruby Muriel Lavallee	Usability Study Identifies Vocabulary, Facets, and Education as Primary Primo Discovery System Interface Problems	2017.0		.htm	text/html	1056	40	37	Although study participants do not completely represent the spectrum of library users at the University of Houston Libraries, adequate information was collected from undergraduate students to inform design decisions that would impact them. The authors note that usability study facilitators provided participants with guidance and prompting to use certain features, which negatively impacts the face validity of the study – completions obtained with facilitator assistance can’t tell us if the user would have been ultimately successful independently navigating the Primo interface, and should have been recorded as incomplete tasks or invalid results.  	cache/eblip-29285.htm	txt/eblip-29285.txt
