Internet has become a must for translation and linguistic researches; the digital processing of the paper dictionaries as well as the online dictionaries are new tools that offer a wide range of possibilities that translators shall learn to understand and use properly. We will focus on the structure of a search in the multilingual site WordReference for the language pair french-spanish, in order to verify its utility for a professional user; in particular, we will check the Forums's applications, where the traditional dictionary is being reinvented in a new collaborative tool for translation. Our aim is to show that the work of the lexicographers can be complemented by the contributions of translators and other language specialists, giving a brand new shape to lexicographic resources.
