In particular, we aimed at providing references for: Residents and visitors who seek to go further in depth than is normally possible with conventional search engines or library catalogs Scientific researchers, particularly those already familiar with generally accessible references, and those interested in finding data and insights from the grey literature not readily located on academic or vendor shelves Participants and students in WMC programs, and their colleagues in universities, schools, and agencies throughout Alaska and the world Individuals seeking to learn more about literature which pre-dates the early 1990s typical era of computerized scientific searches, commonly the early 1990s, recognizing that the Wrangells has a longer history of scientific research than most boreal areas in the western hemisphere. Students and their teachers. The bibliography has its origins in a senior project authored by Vanessa Skean while a student at Alaska Pacific University in 2009, which catalogued the holdings of the Wrangell Mountains Center library, compiled and nurtured by many WMC staff, members, and program alumni over the years. -
