The purpose of this study is to identify the components of information illustration related to user experience in the digital library of Allameh Tabatabai University. The research method is thinking aloud protocol and with a qualitative approach. The study population was undergraduate, graduate and doctoral students who were purposefully selected as a sample population of 30 people. Data collection was performed using Morae software, face-to-face observation, researcher's notebook and users' audio files.
Findings show that elements such as fonts, color combinations, graphic images and their placement and arrangement in library pages have been of interest to users. Problems include not knowing how to use advanced search, as well as the use of a number of image icons. Based on the evidence, elements such as fonts, color combinations, graphic images, and their placement on page have been important to users. Users considered the suggestion of using animated visual symbols to be necessary to make the appearance attractive and facilitate users' information-seeking behavior, which to a large extent overlaps with and is in line with the principles and basis of information visualization. In this way, the use of eye-catching tools such as blinking characters, in turn, can play a key role in identifying important parts. Using fewer visual elements on the front page to increase the focus of the front page, using navigation features on the search page, and displaying a sequence of retrieved records on the results page were some of the common points that users mentioned.
