Research today
Research is carried out by groups of individuals, belonging to different institutions, that dynamically aggregate to carry out projects together
By sharing their resources these individuals create better conditions for their research
Digital libraries that maintain the produced knowledge and make it accessible worldwide are becoming key instruments for scientific collaboration in many research areas
