The entry must emphasize the historical import of the feature, rather than geographical or geological characteristics. All counties shall be included at the entry level. All incorporated communities shall be included at the entry level. All other places of occupation, such as rural communities, ghost towns, etc. To merit an individual entry, an historical event must reflect strong statewide or national significance, rather than strictly local or county-wide significance.
Significance is defined as having contributed to the broader pattern of state history.
Minor historical events should be mentioned in entries dealing with the broader context. Literary works and artistic works may be most properly included under a biographical sketch of the writer or artist, rather than in a separate entry. The most important factor in determining this will be the assessment of the likelihood of an interested reader looking up a work by its title, rather than by author or artist name. Historic objects must have greater than local or county significance. Statewide significance and national significance are recommended.
