Information, documents and texts have been regularly studied for their role in organizing, notably as material artifacts and 'immutable mobiles' (Latour). Yet, stability and immutability can not be considered as intrinsic properties for information. As for interactions (Goffman), objects and infrastructures (Graham & Thrift), information is repaired and maintained. We will investigate two domains of information maintenance: the repair practices of juridical documents in bailiffs offices and the maintenance of data in information security departments of several organizations. Each case highlights a specific logic of maintenance: a repair work from backstage and a distributed awareness of material fragilities. In the first logic, the sociomaterial order is regularly rebuilt through specific cure operations. It rests on a boundary between professionals and ordinary people, experts and laypersons. In the second logic, the sociomaterial order is never performed completely. Information is fragile in essence and everyone has to permanently take care of it
