Objective. Report experiences of applying the lifecycle stages of digital curation to four collections at LIBER Laboratory (Knowledge Technology Laboratory) of Federal University of Pernambuco. Design/Methodology/Approach. The research has a qualitative character and is based on the exploratory study. It was used the case study method, where the processes of a digital curation cycle were planned and applied to the collections of Deliberative Council of SUDENE, the University Television of Recife, the journalist Samarone Lima and the record label Rosenblitz. Results/Discussion. The curatorial cycle was applied to 21,360 documents of the collections, contributing to the preservations of the involved institutions memory and to the initiative of free access to information. It should be emphasized that the collections safeguard information such as bibliographic, archival, administrative, audio-visual, sound, photographic and cartographic documents of cultural and historical value. Conclusions. The processes that involve the useful life of a digital object requires that the institutions and professionals involved in the curatorial processes thinking and rethinking their activities, since acquisition, management, storage, preservation and access are part of a whole and can not be seen in isolation. Originality/Value. While some Brazilian institutions are somehow involved in curatorial activities, many still do not have consolidated standards, staff, or resources to ensure the success and sustainability of such a project, and bring the need for collaboration among institutions. Thus, this experience report presents projects developed in collaboration.
