This issue of School Libraries Worldwide is an open or non-theme issue, focusing on current research from around the world pertaining to aspects of school library practice. The articles in this issue are international in their authorship -- from Scotland, Brazil, Lebanon, the USA and Canada. Yet, in one way or another, each of the four articles is about information literacy, as a concept, a process, and a way of thinking, and about how school library professionals and their clientele interpret and enact that concept in practice.
