The purpose of this paper is to describe the way some of the Spanish general monolingual dictionaries published during the last twelve years have dealt with lexical collocations, that is, those combinations of words that present certain combinatorial restrictions in the norm, basically semantic restrictions, imposed by usage (Corpas 1996). These have been the analyzed dictionaries: Diccionario Salamanca de la lengua espanola, directed by Juan Gutierrez (1996); Diccionario del espanol actual, by Manuel Seco, Olimpia Andres y Gabino Ramos (1999); RAE's Diccionario de la Lengua Espanola (2001); and Gran diccionario de uso del espanol actual. Basado en el Corpus Cumbre, directed by Aquilino Sanchez (2001). We have based our research on a corpus of 52 lexical collocations, which has been built on the analysis of the subentries starting with b in the chosen dictionaries. After that, we have looked up the entries corresponding to each element that constitutes the collocation, in order to know if these dictionaries account for those same combinations in other parts of the lexicographical article. The analysis of the lexicographic information has focused on our aspects: a) the preliminary pages of each dictionary; b) the position of collocations in the lexicographic article; c) the inclusion of these units in a given article; and d) the grammatical category.
