This is mostly useful with links representing hierarchical relation s. As mentioned above , such a cascade of narrower terms is often used with top terms as entry terms. How to Indicate Link Types You can often omit the symbols for the different kinds of links if it is obvious what they are. In a graphic display, different types of links can be represented by different kinds of arrows. In a printed display, you will usually want the entry term to appear at the top left, because this makes it easy to search for.
Variations are possible, though.
In an online display of a single entry, there is more flexibility. Within a group of terms linked in the same way to the entry term, the order is most commonly alphabetical, as in the example just given. Sometimes, however, you may wish to adopt a systematic order by subcategorizing the link types, especially if the lists are very long. Glossary Last updated January 18, 2001.
