The digital exhibitions IMOW developed post-2010 used YouTube to embed video content within each website. The primary issue we encountered is that user-submitted and IMOW-developed content went private, making it unavailable for exhibition visitors. In addition, IMOW embedded content from social media sites as exhibition components; for example, IMOW embedded user-generated exhibition content from the defunct social media platform Storify. While embedding directly from other content-driven social media sites is a great benefit, it can present some challenging issues when considering preservation. As other social media platforms begin to degrade or evolve, websites that host this embedded content may lose contextual information as users elect to leave platforms, delete content, or developers shift platform functionality, leaving broken content in the wake.
