Choosing a good tourist guide?

We plead guilty on each trip, personal or professional, we deploy our talents bloodhound to find a suitable tourist guide. Matter of professionalism, say. Harvesting is sometimes disappointing for dark locations, while for popular places, the choice is vast. In 2015, we wonder when even the traditional tourist guide - on paper - is still the best travel companion.
RECENT PUBLICATION DATE
What could be more practical than a pocket guide that fits easily in a bag (backpack)? These little books can survive a fall and a few coffee stains. You do not fear either of them noted a remark and / or surround certain passages. Not to mention they come in handy for storing tickets, documents and other tickets. In short, they are much more attractive than the bundles of sheets that are self printed from the Internet.
But what are the key criteria? The original publication date is important. Reprint dates are not relevant, or less unless it is explicitly mentioned that the content has been updated. Opt for a maximum wholesale dating guide of a year or a few years. In practice, you will find that cheap guides exist for over 10 years. Better to avoid if you are looking for reliable and timely information.
 WHERE TO BUY? Tour guides will often buy at the place of destination, with still two drawbacks: first, the guide will probably much cheaper at home, and on the other hand, the chance of finding a guide in your language Timbuktu is particularly tenuous, you will agree. The purchase before leaving three advantages: you can find an appropriate guide in advance, start planning / dreaming, and even continue to rummage in the information provided during the journey.
ALL IS NOT UPDATED Never forget that tour guides on paper especially suited for relatively timeless information: history of a country or city, cultural heritage, practical information, travel tips, etc. Their lists restaurants, bars, discos, nightclubs and hotels are otherwise unreliable since these sectors are constantly changing, although each city or destination obviously has its safe bets for restaurants, bars and hotels. In short, travelers who want to stay abreast of the latest news and calculate their budgets on the basis of discounted rates (access to museums, prices bistros and restaurants, public transport, etc.) rather find their happiness on the Internet and in magazines specialized. If you choose to search online, be sure to visit websites that have a good reputation, for example those of the official tourist services (municipal, regional and national). Downloading an app on your smartphone or tablet can also be very useful. The apps dedicated to city trips, with detailed maps (bus, metro, etc.), are especially popular but make sure that they can also be used offline.
TARGET GROUPS AND PURPOSES Also make sure the guides are aimed at different target groups (travel backpack, city, etc.) and make a distinction between a country, region and city. Do not blindly trust the name and under the guide, but open it, browse it and read some passages before you go to the checkout. An overview of available guides you will find tourist guides correct in good bookshops, travel agencies or specialist shops. The following vendors offer excellent guides for various target groups. We have not hired tour guides written by individual specialists or in collaboration with TV channels and / or personalities
