Are you able to pay late fees online? If not, does the library accept partial payments in person or do you have to pay it as a single payment? Is it possible to use wireless connection(via phone, etc.) for printing services?

You have only pay your fees in cash inside. However the integrated option to pay online will be any day now, they even installed the pay yourself credit card machines at the self service stands in the library. They are there and plugged up but software hasnt launched yet. You can also make partial payments of as little or as much as you want. As long as your balance is below $25 you can still check out, use computers/printers and use study/meeting rooms. Once you hit $25 you just have to pay anything to get it back down even if its just a penny to $24.99. So if paying your fees in not possible at the moment but they are still below $25 you have no worries.

From my experience you have to pay in person. I dont think they have online payment features yet which would be vey convient. They do accept partial payments thoufh.
