Notice of Upcoming Content and Access Change

The Museum is working on the future of our online collections access, which will be incrementally released over time. On November 1, 2022, “My Collection” sets will be discontinued and no longer available. If you have “My Collection” sets you wish to preserve, we encourage you to print the sets, save as a PDF, or otherwise make your own copies of important information for your future reference.
