It usually includes all the details related to accommodation, restaurants, transportation and activities. Maps, historical details as well as cultural information are often included. The travel guides are developed from the published personal experiences of aristocrats who traveled across Europe on the Grand Tour. But with today's paperless generation and the emergence of digital technology, many publishers have turned to electric distribution. This may be in the form of downloadable documents to be read on a laptop or handheld device such as a PDA, IPod or online information accessible via a website. These traditional guides like Lonely Planet, Rough Guides, Frommer's, etc. now offer travel guides for download. New online and interactive guides such as TripAdvisor, Wikivoyage and Travelerpoint make their entire guide content searchable by users and make the information in their guides available as free, open content to others.
