Una aclaración Jara.

'Library' no significa librería, sino biblioteca. Es lo que se conoce como 'false friend', palabra cuya forma es similar en ambos idiomas, pero cuyo significado es diferente. La palabra inglesa que debes usar para referirte a una librería (donde se compran libros) es 'bookshop' (inglés británico) o 'bookstore' (inglés americano, como te dice Karlo).

Recuerda:

biblioteca >> library

librería >> bookshop / bookstore
