Hi everyone,

thank you for this great API. My team and I have been working with this api for about one week and we wonder there is any possibility to call api for more than one collection. I've tried with:


but unfortunetly anyone of these is correct. It seems that 'theme' parameter can take only one value.

Dear Kamil,

We are happy to hear of your interest for the Europeana APIs.

At the moment, it is not possible to combine a search in more than one collection... this is because the field "collection" is actually not a field but a (quite complex) query rewrite performed behind the scenes. This is why we do not advertise that "field" but instead designed it as a parameter named "theme" as described in the official documentation:

Btw, we are taking steps to move away from thematic collections (as they were previously called) into a more "entity" driven approach where will augment the data with such information as art, fashion, etc. When this is fully in place, it will open the door to more elaborate queries using boolean/set operations.

We apologize for not being able to meet your needs... if you need any further assistance, please let us know.

With kind regards,
Hugo (Europeana API team)
