By setting up a free Collex account by making a personalized My SiRO page, you can organize your collections, tag and annotate items and share your research using the Exhibit Builder.

Everyday users of SiRO are important contributors to the project. We encourage you to create a My SiRO which will let you collect, tag, and annotate digital objects you locate in SiRO as part of your own research. The tags you apply to objects in your personal collections then become part of the Collex system, helping other users locate and re-purpose scholarly materials.

SiRO is always in search of new projects and digital materials to be aggregated into the Collex interface. If you administer a project having to do with radicalism studies that you would like to be peer-reviewed by the SiRO Editorial & Advisory Board please contact us at
