There are lots of internal reasons to create and maintain an archive. However, sharing your archive can be so much more fulfilling. Sharing the history and details of your work can be a lot of fun, gratifying and rewarding.
We don't all have a gallery space where our archive can be displayed. Do what you can do, when you can do it. Create a page on your website or create a blog where you highlight a different piece every month or create a small display that is placed at your box office and tells the story of one of your previous productions.
Let your light shine.
