Evaluating books finding tools on social media: A case study of aNobii

Some major findings are as follows. While the author browsing function was shown to be most efficient, browsing friends' bookshelves was shown to generate more interesting and informative browsing experiences. Three evaluative dimensions were derived from our study: search experience, search efficiency, and result quality. The disagreement of these measures shows a need for a multi-faceted evaluative framework for these exploration-based navigational tools. Furthermore, interaction effects on performance were found between users' preference characteristics and tools. While users with high preference insight relied more heavily on author browsing to obtain more accurate results, highly involved readers tended percentage wise to examine and select more titles when browsing friends' bookshelves.
