Should you put selections of work from throughout your entire career on your website?
That depends. If your website is meant to be an online retrospective of your art, then yes. But if it’s intended to sell art or get you shows, stick with what you’re doing now. If you want to put up older works, limit them to art that’s reasonably relevant to your present direction, and clearly separate them from your current work. The less relevant it is, the more you should think about leaving it off the website. Plus, you don’t want potential buyers to get interested in art you no longer make. And please– do not put up everything you’ve ever done since your first scribble at age two.
