All Herschel science data, and some user-provided data products, are publicly available through the Herschel Science Archive. Meanwhile, the ALMA Science Archive is being populated with observations from the first three Cycles, with more data released daily. The higher frequency ALMA bands overlap with the lower frequency Herschel bands, and, despite the huge difference in spatial resolution, Herschel sources provide ideal targets for ALMA follow-up. In order to explore the full potential of both archives, archival users need to be aware of the contents and differences.
