University of Lisbon

Crossref memberships (organic units)

Five ULisboa organic units hold Crossref member IDs in their own right, minting DOIs for their journals independently of the rectorate. There is no single institutional Crossref member — the federated-buyer pattern reproduced exactly in the scholarly identifier layer. Crossref is also an enabled external metadata source in the institution's own DSpace deployment.
