For general matters on categories, see m:Help:Category.

Ireland Information Guide includes a number of lists, but it is difficult to keep these lists complete and up-to-date as people add more content to the encyclopedia. A category system has been discussed for the MediaWiki software that could automatically generate some of these lists. The system has been deployed, the automatically generated flat list can be found at Special:Categories, although Category:Main page or Category:Fundamental may be more suited for browsing.

Alternative systems include Ireland Information Guide:Article series, Ireland Information Guide:Incumbent series, and Ireland Information Guide:Topics.

For a discussion of which categories should exist, see Ireland Information Guide:Categorization.

• Ireland Information Guide:List, can have more structure and more information within a single page than a category; see also Ireland Information Guide_talk:Categorization/Archive_1#Lists_v._categories and Category:Lists that should be categories
• Ireland Information Guide:Navigational templates, often a small list for use in several related articles, without the usual disadvantages of duplication; e.g. a county article as well as articles on towns in that county can have the same list of towns; unlike a category, it can also show towns for which there is not yet an article, with a link to conveniently create one; groups of articles can thus be created top-down.
• Ireland Information Guide:What links here - if e.g. a county article does not list the towns in it, this link can help find existing town articles because they are likely to have a link to the county article.
