We started the South America leg of the trip (in Nov 2009) with carrying two books — an old Rough Guide to Southeast Asia and a Spanish textbook/dictionary for Estonian-speakers.
In the countries where we have traveled so far there have hardly been any (English) bookstores (Thailand is different though, as are Australia and New Zealand, but there we didn't stay long). Several hostels have fortunately offered book exchange, where one can drop his/her used travel guide and replace it for a guide used by some other traveler. Apart from travel books also mainstream paperback novels are available.
We have been exchanging a lot but even though the exchange rate has been one-to-one somehow the pile of books has grown over the months. Today it looked like this:
The reason is that we have also acquired several books without exchanging.
Although some of these books have gained sentimental value and useful writings inside (e.g. hotel prices have been updated in the travel guides) over the months they do add considerable weight to our luggage (for which we would probably have to pay extra in our next flight). So we decided to get rid of most of them.
The Banglamphu district in Bangkok is largely a backpacker area with many used bookstores around. From the 10 books that we decided to sell we succeeded with 8 earning 475 THB (= 16 USD). This is equivalent to two dinners in a decent Banglamphu restaurant (or 6 600ml-beers and 10 hot-dogs from a 7-eleven). We asked at 6 bookstores and succeeded in making a deal with three of them:
175 THB
for Brazil, Chile, Laos250 THB
for Südamerika, Ramanujan, Shout!, Language50 THB
for The Lost SymbolTwo books we decided to send home as part of a 8kg package:
Lonely Planet Cambodia we exchanged for Satanic Verses at our guesthouse. Both are Southeast Asian photocopies, not original versions.
So, four books remain:
