Browsing tips:

Popup structures	Interactive link maps	Ring index
Underlined linear structures display the actual structure of the molecule when you put a mouse cursor over them.	Each entry contains interactive maps of its references and referees, thus making navigation through related terms very convenient.	All ring-containing structures in the Gold Book were split to individual rings and these were organized in a comprehensive ring index.
