WEBREVIEW http://www.webreview.dz/ Webreview est un site fédérateur des revues scientifiques. Il met à la disposition des utilisateurs un ensemble de revues scientifiques algériennes couvrant tous les domaines. Webreview est ouvert à toute revue désireuse de publier son contenu en ligne soit en mode d'accès complet ou restreint permettant ainsi la valorisation de la recherche scientifique en Algérie. Webreview et un projet développé par le CERIST au sein de la Division Recherche et Développement en Sciences de l'Information.
