Alder develops digital content and has overseen the creation of websites for various history projects.
"Uprooted: Japanese American Farm Labor Camps During World War II" is a traveling photograph exhibit. Part of the project included the creation of a comprehensive website and a short documentary film. The website provides additional resources to audiences, such as video clips and transcripts from oral history interviews, lesson plans, research materials, and details about upcoming exhibit venues. Alder created all the content for the site, working directly with a graphic designer and a web developer.
The History of Medicine in Oregon Project was established in 2001 by the Oregon Medical Education Foundation, with the goals of collecting, documenting, interpreting, and presenting stories of medicine in what is now the state of Oregon, to provide the medical community and the general public with a deeper understanding of what has been tried in the past and the challenges that lie ahead. Alder joined the project's steering committee in early 2012 to provide historical expertise. A website launched in October 2012, with content researched and written by Alder. The site will be continuously updated as the project works toward future publications and digital content.
The Center for Women, Politics & Policy has launched two digital exhibits in which Alder has served as the curator. The exhibits draw from the Oregon Political Leadership Archive, a partnership between the center, Portland State University Library, the Department of History, and the Black Studies Department. The exhibits include: "Expanding Access," an overview of the archive, and "A Sea Change in Oregon Politics," in celebration the fortieth anniversary of the 1973 Oregon Legislative Session.
Working alongside Oregon Historical Society staff, Alder updated a series of narratives featured on the Oregon History Project website.
