Wikipedia:Organizing disambiguation pages by subject area
On large disambiguation pages, organizing by subject area helps readers find the page they want. Readers should be able to find their target article with a minimum amount of reading, by skipping irrelevant sections, and narrowing down from the whole page to one section, to one subsection (if present), to one entry. This page discusses three principles that enable that goal, and suggested headings to use. Guidance for individual entries is at Wikipedia:Manual of Style/Disambiguation pages.
This is an explanatory supplement to the Wikipedia:Manual of Style/Disambiguation pages § Grouping by subject area.
