Helmet-kirjastojen aineistot Finna-palvelussa

From the dataset abstract

Data from the HelMet libraries’ catalogue in a machine-readable format. The data source contains the descriptions of approximately 680,000 books, records, sheet music publications and other materials found in the Helmet library system (the city libraries of Helsinki, Espoo, Vantaa and Kauniainen).

No new Helmet catalogue is available at this time. However, the National Library’s Finna portal has an open API through which you can search for the material data of Helmet libraries.
