Your gateway to millions of microforms and digital reproductions of books


Please note: This page is still in development.

With just a little scripting, you can plug EROMM Request into your local Document Order and Delivery System or ILS or even build your own application to maintain your incoming requests. The EROMM Request API consists of a number of (RESTful) webservices which will return JSON objects as default (or HTML if you explicitly ask for it).

Supported HTTP commands are GET and POST, which can be used alike. You may either use querystring parameters in your HTTP-requests or pack the parameters into a JSON object, which is then handed over as the value of the parameter data. If you use both variants in one request, the querystring parameters will take precedence over the JSON encoded values if there is a conflict.

Please note: Please consider this API sort of “beta”. We might change a thing or fix a bug in the future and will announce it on the EROMM Website accordingly. If you let us know, that you are using the API, we could inform you directly in advance. Please note also that this documentation documents only these parts of the API that are needed on the supplier (i.e. the library or institution holding a microfilm or digital item a user might be interested in) side. We might publish the other parts at a later point in time.


Common parameters for all API calls:

cmdCommandindicates the action that should be carried out.
authAuthentication Token Any action that requires the client to be authenticated, needs an authentication token being sent with the request. This token is obtained by performing a login operation.
formatOutput formatSpecifies the response format of the API call. Currently json and html are supported, with json being the default if no format indication is given.
