Weekdays from 9am – 5pm
All visitors must enter the building from the south-most door on the 34th St. porch. Penn affiliates should present their PennCards to the security guard for inspection before proceeding to the library, and a visible PennCard must be worn above the waist at all times while in the building. The Chemistry Library is open by appointment only to scholars from other institutions and members of the general public on weekdays, from 9:00 am - 4:30 pm. Anyone wishing to make an appointment should do so by contacting the Chemistry Library at (215) 898-2177 or chemlib@pobox.upenn.edu. Upon arrival, they must display a valid photo ID card and sign in with the security guard, who will impart further instructions.
Weekdays from 5pm to 10pm
Access is restricted to holders of department-validated PennCards, which must be worn in a visible location above the waist at all times while in the building.
Weekends/Holidays
Access is by validated PennCard only. PennCards should be worn in a visible location above the waist at all times while in the building.
To validate your PennCard:
Cards are validated by advance arrangement with the Chemistry Department. Go to the Chemistry Department Office (first floor), Monday - Friday, 9am - 4pm, bringing your PennCard, and request access to the Chemistry Building for all hours that the library is open. Alternatively, you may e-mail Judith Currano with your name and ID number, and she will forward the information to the Department.
Validation is tied to the life of the PennCard, so, if you get a new card, you must have it revalidated.
