Denali is six million acres of wild land, bisected by one ribbon of road. Travelers along it see the relatively low-elevation taiga forest give way to high alpine tundra and snowy mountains, culminating in North America's tallest peak, 20,310' Denali. Wild animals large and small roam un-fenced lands, living as they have for ages. Solitude, tranquility and wilderness await.
This is a list of no-cost sources that list or index electronic texts, including journal articles or reports. At these sites you'll find electronic books, journal articles, scientific and technical reports, conference papers, fact sheets, news transcripts, preprints, theses and dissertations. Many provide the full texts online, or abstracts, while others merely list bibliographic citations.
Employees of the U.S. Department of the Interior are reminded they may also search for journal articles by using EBSCO Online, GREENR, JSTOR, or Science Direct. Most employees may search these databases at their desks, while others must come to the Library or contact a Reference Librarian for assistance.
