Aug 2023: Editors’ Note on Updating Content

The built environment is in constant flux, whether from demolition and new construction, renovations and additions, or changing function and use. Social protest and cultural progress also transform the built environment, as we have witnessed in efforts to remove Confederate monuments from public spaces. The effects of climate change are equally consequential, with flooding and wildfires imperiling, damaging, and destroying significant buildings and sites with increasing frequency.

As a digital publication, SAH Archipedia strives to ensure that its content is up to date and that published texts accurately reflect physical conditions on the ground. To that end, our editors and authors are reviewing individual entries and essays to identify those that need to be updated.

While this work is ongoing and continuous, we want our readers to know that we are prioritizing updates to entries and essays (and illustrations and metadata) dealing with monuments to white supremacy and memorials that otherwise symbolize oppression to indicate (1) the removal of statues and other forms of dismantling or transformation, (2) the renaming or retitling of buildings, parks, plazas, bridges, streets, and highways, (3) necessary contextualizing and interpretations in light of new historical research and scholarship. We are also prioritizing updates to entries and essays that deal with buildings and sites that have changed as a result of extreme weather events.

As always, SAH Archipedia’s editors will work with authors and peer reviewers to maintain the highest standards of a scholarly publication.
