Most, if not all, of the other reviews have mentioned the egregious omission of an interactive map of the museum (and the Cloisters), so Ill simply mention that it should be the Digital Departments highest priority moving forward.
Just as important, however, is access to the entire collection database— or at the very least, that which is available online. I am slightly insulted that the objects are pre-curated for me in cutesy categories (Met-staches? Please.) instead of me being able to access the records of any object-- on view or not-- myself.
