Due to the growth in both the number and use of e-books, the question arises as to which factors may influence information professionals and library and information science (LIS) students when considering adopting e-books in their organizations. This study uses the technology acceptance model (TAM), a well-known theory for explaining individuals' technology behaviors, and cognitive appraisal theory as theoretical bases from which to predict factors that may influence information professionals and LIS students in their adoption of e-books in their organizations. This study explored two main themes: whether there are differences between information professionals' and LIS students' perspectives towards e-books, and to what extent the TAM, as well as other personal characteristics such as threat, challenge, and motivation, explain information professionals' and LIS students' perspectives. Researchers used questionnaires to gather data on computer competence, attitudes to ebooks, motivation, and cognitive appraisal. Findings reveal that there are major differences between the two groups concerning computer competence, motivation, and challenge. In addition, the TAM, as well as other personal characteristics, can predict the likelihood of e-book adoption, and highlights the importance of individual characteristics when considering technology acceptance.
