To work at Grimm Library, you don't even need an id or anything. Just go there. But they have some rules about main times of the day like 8-19 reserved for actual students - although I never experienced anybody controlling it.

I go there for anti-procrastination as well, it's great.

Some of the university libraries in Berlin are quite strict about what you're allowed to bring in (ie, no bags of any size). Fortunately, the Amerika-Gedenk-Bibliothek is close by and if they have such policies, they certainly don't enforce them.

Haven't been to the Grimm yet, but I remember passing by on the S-Bahn maybe a year ago and being excited about the huge new library under construction...I'm not in Mitte very often.
