Ljubljana’s main library, the Oton Župančič, marked red on the map at the end of this text, is centrally located and rather large, with a lot books in English and other languages, and an audio-visual section in the basement. It’s somewhat tucked away, at Kersnikova ulica 2, but near the club K4, a Berlitz school an interesting Russian candy and other delights store (1000 Slaščic) that sells sweets pick’n’mix style, if you want something to illicitly munch on while browsing. The floors are a lot of fun to explore, although you’ll need a library card, or at least a number, to get the most from its stacks and shelves.

To get this you’ll need an Urbana card, the same as you’d use for the city buses, bikes and many other amenities. If you don’t have one, you can buy one for 2 EUR at the library (4 if you need a replacement). You then pay 15 EUR for a year’s membership (9 if a student, free for children). Books can be checked out for three weeks, and a few days before the due date you’ll get an email warning you of this. You can renew each book once online, after logging in at the My Library section of the website. The catalogue can also be searched online, and reservations made, although the English version of the site it buggier than the Slovene. Details of prices for more services, as well fines, can be found in English here.
Finally, the opening hours for the Oton Župančič Library are Mon, Wed—Fri 08:00–20:00; Tue 10:00–20:00; Sat 08:-00–13:00. Those for the other branches, also marked on the map differ slightly.
