Every year, the province of Cordoba holds a book fair in Plaza San Martin. The fair is sponsored by the provincial government, Holiday Inn, and local banks. You’ll find all types of genres like science fiction, suspense, horror, young adult, romance, religious, anime, graphic novels, cookbooks, college textbooks and children’s books.
There's a café in one of the tents, where people can sit a bit and read the book they purchased, but unfortunately, I found nothing to read in English.
The only thing you’re not likely to find is an abundance of books written in international languages, such as English. Novels like Interview with the Vampire, The Lord of the Rings Trilogy, Twilight, City of Bones, or Vampire Diaries are only available in Spanish.
Even if books don’t interest you that much, take some time to do a little sightseeing in Plaza San Martin in the evening. It's beautiful. The book fair, known as Feria de Libros, is held in the beginning of September and lasts about two weeks. So, mark your calendars for 2014 and check it out!
