CrossRef is on of the DOI registration agencies, responsible for scholarly and professional publications; with more than 2000 publishers participating. The participating publishers register metadata records for each each DOI and thereby built a big multidisciplinary reference database with more than 29 million records.
The most usage scenarios described below require that the institution become an CrossRef affiliate, e.g. by signing the

Conditions: There is no charge for most libraries to get a CrossRef account to retrieve DOIs or metadata, but there is a fee for high-volume (> 1 million) requests - affiliate agreement, see http://www.crossref.org/04intermediaries/index.html
Conditions: annual fee according to price list.
The MPG is a CrossRef affiliate, more information is available via Inga.
Fetching Metadata[edit]
CrossRef supports various methods to request the metadata for a known doi.
via the OpenURL interface[edit]
The OpenURL interface provides an convenient way to access the metadata record for a known DOI. Currently this interface does not require users to have an account, but this is subject to change.
Example request (crossref_query output): http://www.crossref.org/openurl/?id=doi:10.1007%2F978-3-540-73859-6_29&redirect=false Example request (unixref output): http://www.crossref.org/openurl/?id=doi:10.1007%2F978-3-540-73859-6_29&format=unixref&redirect=false
More information: http://www.crossref.org/openurl_info.html
via an OAI interface[edit]
CrossRef operates an OAI-PMH service provider for distributing metadata to subscribers which is especially helpful for a bulk download of metadata records. Accessing this interface requires an additional agreement which is currently not avilabl
Example request (identify): http://oai.crossref.org/OAIHandler/?verb=Identify Example request (record, login required): http://oai.crossref.org/OAIHandler/?verb=GetRecord&metadataPrefix=cr_unixml&identifier=info:doi/10.1038/42304
More information: http://www.crossref.org/webservices.html
Available Outputs[edit]
crossref_query output: the . Schema: http://www.crossref.org/qrschema/crossref_query_output2.0.xsd
unixref output: a more verbose XML response. Schema: http://www.crossref.org/schema/unixref1.0.xsd
Additional Tools[edit]
doi resolver (provide a doi and be redirected to the corresponding article location): http://dx.doi.org
free doi lookup (provide metadata and receive the corresponding doi): http://www.crossref.org/guestquery/
Crossref simple text query (provide a reference): http://www.crossref.org/SimpleTextQuery/
