"See also" Cross-references

"See also" cross-references assist the user to quickly navigate to the right index term. The same principles that apply to "See also" cross-references apply equally to hypertext linking. "See also" cross-references are constructed using the following relationships:
  • a broader term to a narrower term, e.g. 

  • mammals, See also whales
    sailing craft, See also hulls
  • overlapping meaning between two terms, e.g. 

  • gold, See also money
Sometimes the broader/narrower term relationship is reversible, depending upon how you think about it. In this case, you may wish to create "See also" cross-references in both directions, e.g.

steam power, See also trains

trains, See also steam power

Where the meaning of terms overlap, such as gold and money, you can create  "See also" cross-references in both directions, e.g.

gold, See also money

money, See also gold

Other overlapping terms only make sense in one direction, e.g.
population control, See also family planning
Someone searching for family planning is unlikely to be interested in population control.

If you have synonyms, consider using a "See" cross-reference, e.g. 

folders. See directories

Don’t send the user on a wild goose chase! Avoid "See also" cross-references from narrower to broader terms, e.g. car, See also transportation. Similarly, avoid horizontal references as well, e.g. wheels, See also engines.

Remember, the "See also" cross-reference directs the user to more detail about a topic.
