Each section contains original articles written by academicians, scientists, science undergraduate students, and freelance writers. All articles written specifically for Action Bioscience undergo independent peer review prior to publication; articles by students are reviewed by educators or other professionals. The only feature that could use improvement is a site directory which contains a laundry list of more than 140 topics. Subheadings or subtitles would have been helpful.
A List Apart
An online magazine that covers Web content and development, including design, standards, coding, and accessibility issues. A number of editors run the site and accept submitted articles based on the magazine's stated guidelines. It is a great publication for practitioners, but not for the beginner or casual Web Designer, since some of the article discussions are quite technical.
Aldo Leopold Archives
University of Wisconsin; provides access to the written works of one of the great early 20th Century conservationists; consists of digitized resources from Leopold's main body of work from the end of the 19th century until his death in 1948; users can search the collection by title, author and illustration; Boolean and proximity search is also available.
Allium Central
The genus Allium--ornamental onion--includes many attractive, underused flowering plants. Site is reasonably organized but some sections such as Dwarf Alliums only have a placeholder title; the site is attractive with photographs and information not easily found elsewhere online...but it is incomplete in several areas. : American Medical News

Most of the resources listed are intended for researchers, teachers, and students, but some are labeled for beginners, i.e., those with an interest in a topic, but with little or no education.
Calculus Animations
The visualizations in Calculus Animations could be useful for students studying calculus or as a supplement for instructors to use for demonstrating the rotation of equations about axes. 260 animations are available, all posted in AVI format, so users can view in QuickTime, RealAudio and Windows Media, but not with Winamp.
Carbon Offset Research & Education (CORE)
Delving into the often-confusing world of carbon offset programs and research, CORE compiles data from authoritative governmental bodies and international organizations (e.g., US Environmental Protection Agency, World Bank, UN, and World Wildlife Fund). However, the site states that CORE does not reflect the views of these institutions nor does it obtain any official endorsements from them. An initiative of the Stockholm Environment Institute, CORE provides plenty of data regarding various types of legislation regarding carbon offset programs, both in the US and abroad. The site also includes a decent glossary to help the user navigate through the world of carbon offset and the policies and regulations that define it.
CDC Wonder
WONDER (Wide-ranging Online Data for Epidemiologic Research) online databases utilize rich ad-hoc query systems for the analysis of public health data.

from the College of Physicians of Philadelphia; This site is an excellent resource for information on the history of vaccines. Although some content may be available through other sources, the site's greatest strengths are its excellent use of multimedia and its provision of vaccine-related primary documents....Although aimed at a high school audience, this resource offers considerable content that would be useful as background information for lower-level college students. Additionally, some of the activities or videos could be integrated into the college classroom.
Information Bridge
DOE Scientific and Technical Information; a free, full-text, public access database created in 1998, is an ongoing digitization project of technical reports and documents from the US Department of Energy (DOE). Because an informed citizenry is essential to a sound energy policy, the DOE's Office of Scientific and Technical Information (OSTI) developed IB to support the agency's commitment to scientific discourse. IB is a niche collection....[However,] with more than 266,000 full-text documents and bibliographic citations, IB includes a broad range of topics, including physics, chemistry, biology, environmental sciences, renewable energy and energy technology, materials science, engineering, computing and information science, and other areas central to DOE's mission of advancing energy-related science and technology.

The site contains more than 28,000 videos representing 5,500 species and continues to grow. Browsing is hierarchical and starts with orders and then families. The database is punctuation sensitive--that is if a common name includes a hyphen (black-capped chickadee, etc.) the hyphen must be included in the search request or no results will be retrieved. The IBC's ranking tab allows video sorting by average user rating, which is often quite helpful. The IBC is the only site containing such a large collection of bird videos.
