General Information

  • You don't have to register/login to browse the items in the Sigma Repository. It's true! Just start browsing and searching.
  • Most of the items in the Sigma Repository have attached files that are available to view immediately.
  • There are a few item records with files that are embargoed (i.e., locked down for a period of time). These files are designated with a closed lock symbol. They represent the minority of item files in this repository. Registering and logging in does not open these files. The files will open to the public on an individually preset date. Usually, 18 to 24 months after the posting date.
