The National Geographic Virtual Library contains every page of every National Geographic Magazine ever published. It includes National Geographic Traveler from 2010 to present, National Geographic Kids from 2009 on, and many National Geographic Books. It has a cross-searchable platform, so you can search all publications at once, or you can limit your search by publication title, content type, image type (29 different image types!), and publication date. Individuals or groups can open accounts to create tags and save documents. Group accounts allow students working on projects together simultaneous access to tag, save, and share documents.
You can find NGVL in several places:
In Research, it’s under Magazines & Newspapers and Travel. It can be found in Teen Homework Resources under Science & Health and Social Studies, and in Kids Homework Help, it’s under Science and States & Countries.
