I came here a couple days after Livraria Bertrand (the oldest continuously operating bookstore in the world) and I kind of preferred this one, actually.
Don't get me wrong they're both wonderful, but this one has a more authentic local bookstore feel. A bit grimier, messier, minimal lighting inside, overall a bit more history in its walls. I love it. Less tourists too, and that's never a bad thing.
I tried looking for a particular book at Bertrand called "Salazar: The Dictator Who Refused to Die" by Tom Gallagher. I couldn't find it there so I came here and I found it right away.
In my experience in other countries that have had their share of history with authoritarianism, finding books on the subject isn't always easy. I'm not sure if it has to do with willful ignorance, or being in the wrong place at the wrong time, but it's refreshing to find a book about this Portuguese dictator, in Portugal, and in English for a tourist like myself to be able to read. Portugal is a fascinating country with a rich history, and finding books like these - that happen to discuss hard and unflattering topics - only makes me respect them more.
