Objective: This paper reports on the most notable examples of library projects using augmented reality technology, focusing on the results, the contributions this technology has made and the various difficulties librarians should bear in mind when planning such projects.
Methodology: The paper provides a literature review and analyses a series of projects.
Results: Although augmented reality (AR) technology is still relatively new, its use in library projects is becoming more widespread. However, we need to consider not only how such projects have succeeded but how they reflect the difficulties of applying AR in a library context. This paper provides library professionals with a description of the pros and cons of the various uses of AR, grouping these into seven sections, according to application: geolocation; the use of AR to provide historical context; exhibitions and other activities; publications; the use of AR to enhance of physical spaces; literacy and recreational use; and professional applications.
