I know from the "Food and Drink" section of Maroon Opinions that concerns about eating in the libraries are ongoing, but if adding mine helps reach the critical mass needed to take aggressive action on this, then I'm all in. Every day I see blatant disregard for the food ban in the libraries--more than just a snack. I am less concerned, frankly, about the noise and odor than I am about the real reason the libraries forbid eating: concerns about pests and the damage to books. I've had to pass over tables and carrels that are too greasy to spread books on and I'm appalled at the mess and flagrant disregard of this important rule.
No one wants to be the food police, but something should be done. I recognize that someone is thinking about this, because I see more and more signs that say "No eating in the library." I also recognize that finding a place to eat lunch on this campus when outside isn't an option is nearly impossible. The Reynolds Club and the basements of Crerar and Stuart are about the only places one can even begin to look for a place to sit and I seldom find a place at lunch. Still, I think that the food bans in the libraries are very important and need to be enforced.
As you point out, dealing with food and drink in the Library is an ongoing problem. We have tried to put out more signs (and more visible signs -- thank you for noticing), but beyond reminding people of the official policy and encouraging offenders to take their food to Ex Libris, we're fairly limited in our options at present.
Some would say that we conceded the pest issue and concerns over book damage when we put a coffee shop inside the Reg, since nothing stops patrons from bringing Library materials into Ex Libris for reading along with their donut or panini.
This being said, if you notice a particularly egregious violation of the food policy, feel free to involve the nearest Library staff member. We can also ask the custodians to pay special attention to a particular desk or carrel during their cleaning, if necessary.
