That is true. However according to my experience you don’t need to spend much time in the library itself if you know what you’re looking for (you can always stay for the atmosphere). What takes time is going to and from the library. The value of this time obviously depends on a lot of parameters: is the library close to your route to/from some other place, are you currently very busy, do you enjoy city walks/bike-rides, etc.
