Altweb, the Alternatives to Animal Testing Web Site, was created to serve as a gateway to alternatives news, information, and resources on the Internet and beyond. Altweb now is the U.S. home of the journal ALTEX: Alternatives to Animal Experimentation, which is the official publication of the Johns Hopkins Center for Alternatives to Animal Testing (CAAT).

Altweb is intended to serve:

  • Biomedical researchers
  • Industry
  • The international alternatives community
  • The international regulatory community(ies)
  • IACUCs and other institutional groups that review animal protocols
  • The animal welfare community
  • Individuals and groups who work with laboratory animals (technicians, veterinarians, etc.)
  • Educators
  • Students
  • The general public

Altweb has five practical goals:

  1. To assist scientists and others seeking to conduct a search for alternatives methods.
  2. to serve as a CRP—"central reference point"—for alternatives information, publications, databases, calendars, and other resources.
  3. to support the creation and maintenance of new alternative resources as needed, when no other organization can/will do so
  4. to promote the use of alternatives resources by publicizing them on the site and through e-mail or other outreach
  5. to facilitate communication and collaboration among members of the alternatives community, in particular those who work in database or information management.
