Dublin City has removed all Library Fines from 01 January 2019 and even if you have an outstanding debt, your slate will be wiped clean. The intention is to get more people to use the libraries, but the strategy seems very odd!
Loaning books is free and you only have to pay if you keep them longer than the loan period. Once that period has passed (and I think the period is pretty long 3 weeks!) then you had to pay 5 cent per day up to a maximum of EUR 3. Not super expensive, but a tool to ensure that the books are brought back in time.
How will the waiving of the fees get more people to use the library? Only if they were afraid to use the library because of the fees otherwise nothing will change for them. OR if they stopped using the library because they had a big bill waiting for them.
I VERY much doubt that anyone would not use the library because of a cost of 5 cent per day IF you are late (and by the way, in most cases you can extend the loan period for free over the phone). VERY unlikely that this fear really holds anyone back.
Dublin City Libraries do a great job, but this is a silly strategy that will not bring additional users to the libraries.
