The question of preservation and perennisation of documentary heritage of archives libraries has always been the mains worries and debates of professionals of information-documentation and now more than ever interests users. This is in line with the importance societies give to History and Memory. This return to the past is only possible if the relevant prove (mainly archives) is well kept and given value. Digitalization opened new ways to save the heritage, especially in the context of Southern countries where the conditions of conservation are challenging due to unfavorable tropical climate and due to the fact that infrastructure and material means are often lacking. The solutions offered by digitalization for the saving, perennisation and the access to documentary heritage are somewhat satisfactory, but they do not give all guaranties especially for the fragile and precious historical documents like the master copies of archives on slavery and colonization.
