Buy the Chapter is a service from Lonely Planet that lets you purchase digital copies (PDF files) of single chapters from many of their travel and language books. I just bought the Slovak chapter of their Eastern Europe Phrasebook and the East Slovakia chapter of their Czech & Slovak Republics guidebook. Total cost was $5.00 for both.

No need to haul heavy books around the planet. No need to buy all sorts of content for places I’m not visiting. Much paper and shipping saved. And because they’re PDF files I just dropped them onto my Nokia N95 mobile phone, which has a PDF reader, and I’m ready to haggle (Aká ke vasa najnizsia cena?), pee (Kde sú tu záchody?) and ask for Milana Lasicu records (Hľadám niečo od Milana Lasicu).
