The SaLamander Project
The Salamander Project is a collaborative effort by librarians and educators for developing a taxonomy of sites and tools useful for teaching and learning in Second Life.
The SaLamander HUD (heads-up display) is free for download in Second Life. It functions like a user-interface for searching and tagging in-world resources. Resources deemed most useful by reviewers will be transferred to the MERLOT (Multimedia Educational Resources for Learning and Online Teaching) database -- a learning objects repository.
