Items in the bibliography are assigned a Category, i.e., a topic. Click on a category to find all the items in that category. This helps you find all the items in the subject area you are interested in. Categories appear to the left of each annotation and in a list on the right side of this screen.
Each item in the bibliography is also assigned a set of Tags, i.e., descriptors, that describe the content of the item. Click on a tag to find all items that have similar or related themes. In this bibliography we have included each author’s last name as a tag to help you easily find all items by the same author. Tags appear below the category to the left of each annotation.
When you click on a link it will open in a new tab in your browser. This makes it easier to return quickly to the main bibliography page.
