English translations of Latin American titles can be found in the Library catalog under the English title. If you do not know the title of the English translation, do a title search under the Spanish title to determine whether the Library has the English translation. For example:
Amor en los tiempos del colera by Colombian author, Gabriel Garcia Marquez, has been translated into English with the title: Love in the time of cholera. A title search either under Love in the time of cholera or Amor en los tiempos del colera lets you determine whether the Library has the English translation.
