Stern talks about shared workspace collaboration tools and describes the use of a shared workspace for manipulating multiple media materials and the sharing of real-time workstation screens to understand and demonstrate more sophisticated search methods and to facilitate the mastery of more advanced tools and techniques.While increasing collaboration and interaction at a distance, remote control is also the next step in offering advanced instruction, assistance, and collaboration. The next two presentations include reference librarians who partnered with a library technical support analyst and a vendor to develop a tablet-based app and a mobile app to extend reference service. The last talk focuses on how an ask-a-librarian service leverages the time and expertise of EPA librarians across the country to present a unified service to all EPA staff. It shares lessons learned during the last 3 years and future plans.
