Comment: The article is not especially concerned with dictionary matters such as the etymology or grammar of the term.  The bulk of the content explains how the concept applies in various fields.   The concept appears in the title of numerous works such as ''In Situ Hybridization Histochemistry''; ''Plant Genetic Conservation: The in situ approach''; ''In Situ Assessment of Structural Timber''; ''In Situ Remediation Engineering''; &c.  The concept is therefore quite important and a high-level page of this kind is helpful in bringing such common ideas together somewhat like a |dab page
