There's nothing wrong with Coimbra's library. It's a nice library. It's just a woefully small library considering that it's in a city known for its university. In other university cities you might not need an impressive city library, since people can just use the university library. Not so in Coimbra, where the university library requires timed admission tickets because it's a highlight on everyone's tour of Portugal.
So, non-students need to use the city library. Which doesn't even have its own building. When you enter the building the main library is on the ground floor to the left. The children's library is down the stairs to your left. The toilets are on the ground floor to your right.
The main library has two rooms. The first room has a little art exhibition area, which currently has historic photos of the flood. There are periodicals and comfy chairs. There's a little mezzanine that rings the room. Then the second room has tables for people to work at, which is frequently quite busy, although you can always find a place. There's a daisy chain of extension cords providing power to the tables. The wifi seems reliable. Both rooms have a selection of books. A little bit of everything.
I understand not every city has an architectural gem as their library. That not every city has a dozen libraries and a huge collection of books. Still, it's quite confusing that Coimbra's library is smaller than the library of the town I grew up in, population 25k. read more
