Portuguese municipal archives are using Facebook to provide global access to regional and local information. A content analysis of 14 municipal archive Facebook pages over 20 months found that the number of likes ranged from 1,166 for the large city of Lisbon to 5,508 for a small town. The number of publications in that time ranged from 0 to over 100. Subjects of publications included general issues, availability of documents, digital objects, municipality-specific topics, and local history, culture and education. Comments on posts varied widely between archives. The conclusion is that archives play a vital role as living memories of local communities by sharing information online.
