Of course.

I mean, no one is going to do calculus sober

Cognac and study

It’s the carbonation induced volcano they’re trying to avoid

More of a Scotch person myself.

Of course. But for gods sake - no seltzers!

They have a resealable top. The library is most likely concerned about spills. Most of them have a no cans policy.

Opening cans is very distracting.

There's other good speculation on the reasoning but I wonder if it's due to the younger staff put in charge of posting this notice. Maybe they pestered management about the specific reasoning until they determined that hard liquor did not meet the provided definition of restricted items, then added the last sentence as a form of protest.

Duh, obviously you need hard liquor for hard study. It's pretty hard.

I assumed it's because the tenured faculty come in to do their research with a pocket flask.

Don't mess with the hard liquor lobby. If you know, you know

In my experience the library is often visited by homeless people because it's free entertainment. A lot of the homeless people around my area are also alcoholics and have you ever tried to take alcohol away from an alcoholic. It's not easy.

if that were the case they could just write "no canned beverages" or "no drinks without resealable lids" etc. there's no reason to bring booze into it at all. so if that was their intent then this is really poor communication.

Fizzy drinks in cans can erupt like a volcano too

Alcoholic?

Boozey iced teas

The real pro tips are always in the comments.

Okay but drink it from the bottle. No spills!

Im guessing literature professors.
