As K-12 schools increase the presence of and access to technology, the role of school librarians is changing. Many librarians have not been prepared by their colleges and universities for the changes demanded by their jobs. In this article, we discuss the skills that 47 school librarians reported having learned on the job as opposed to in librarian preparation programs. More than half indicated that they had to develop technological skills while on the job. This can be explained by technology's influence on society, librarians being early adopters and leaders of technology and technology's ability to enable learning. Because of these technological skills indicated by school librarians, we provide resources and share suggestions for how school librarians can build a Professional Learning Network (PLN) to learn about and with technology.
