Add filters for item type

Resource (e.g. The Nature of Code) vs project (e.g. cool thing that uses concepts from The Nature of Code) – although some overlap?

Filters for work from CCC members?

IDK if same issue or different, but could the tags on the right also be clickable to resort the list? I noticed when using the site that was my first impulse, could be useful. As far as resource vs project, would we just tag a project as both, or tag it with the name of the book too?
