  • 38. Search for it Publisher Site Reference to article
  • 39. How do I nd CrossRef DOIs? •For People • For Systems • Simple Text Query • Open URL Lookup • Guest Query • CrossRef Query System • CrossRef Metadata Search (pilot) • CrossRef Metadata Service • Blog Plugin (pilot) • Firefox Search plug-in (pilot)
  • 40. Do not attempt to derive CrossRef DOIs! 29 Source: alexliivet from Flickr
  • 41. http://www.crossref.org/help/CrossRef_Help.htm
  • 42. Simple-Text Query • A freely available, easy-to-use tool to retrieve DOIs. • A custom version of Inera’s eXtyles® refXpress parses unstructured references into granular, valid XML and returns any matching DOIs for those references • NOT for bulk use for individuals looking for a DOI • There is NO programmatic interface to this service
  • 43. Guest Query • Also a freely available, easy-to-use tool to retrieve DOIs. • A fielded search form where you enter bibliographic data.
  • 44. http://www.crossref.org/guestquery/
  • 45. CrossRef Metadata Search • Also a freely available, easy-to-use tool to retrieve DOIs • A pilot project with a simple search interface • Retrieval technology is different from Simple Text Query and Guest Query-- may return different results • An API is available
  • 46. http://labs.crossref.org/site/crossref_metadata_search.html
  • 47. This service does have an API www.crossref.org/sigg/sigg/help
  • 48. … MORE
  • 49. Firefox Search Plugin • Also a freely available, easy-to-use tool to retrieve DOIs • A pilot project--not a production tool • An Open Search tool that allows their browser search CrossRef Metadata from users to search bar.
  • 50. Blog Plugin • Also a freely available, easy-to-use tool to retrieve DOIs • A pilot tool rather than a production service • Works with WordPress • A tool for bloggers to look up DOIs in their authoring environment
  • 51. The formatted and linked citation is inserted at the cursor position.
  • 52. Open URL Interface -for systems • A free service for libraries • Must register a valid email address to use at http://www.crossref.org/requestaccount/
  • 53. DOI and OpenURL • OpenURL is workan alternative to CrossRef and DOIs – they not together • The DOI system and CrossRef are OpenURL aware; therefore publishers are OpenURL enabled via use of CrossRef and DOIs
  • 54. Appropriate Copy Problem Local OPAC Aggregator
  • 55. Localized Linking via DOI Redirection • Library installs local linking server • User in library context clicks on a DOI link • A “cookie” on user’s machine alerts DOIserver server to redirect this DOI to the local linking proxy • Article-level metadata neededthe link orresolution can come from the source of for local from CrossRef via OpenURL
  • 56. Where is the magic? Here! DX.DOI.ORG OpenURL Aware Registering the IP address of your http://dx.doi.org/ Local Link Server via CrossRef doi=10.1034/j. tells the DX resolver to send links 1399-0039.2000.560502.x back to the LLS and not on to the http://REGISTERED-ADDRESS/? publisher. doi=10.1034/j.1399-0039.2000.560502.x DOI Metadata Server
  • 57. CrossRef OpenURL Parameters Metadata &aulast &title &volume &issue &spage &date &issn

  • 59. OpenURL directs to URL by default
  • 60. http://www.crossref.org/openurl/? title=Biochemistry &aulast=Wireman &volume=13 &spage=1215 &date=1974 &redirect=false &pid=email@address.com

  • 63. OpenURLs also work with minimal metadata http://www.crossref.org/openurl/? &aulast=Wireman &title=Properties of 30S ribosomal particles reconstituted from precursor 16S ribonucleic acid &redirect=false &format=unixref &pid=email@address.com
  • 64. And if you have the DOI and want the metadata … http://www.crossref.org/ openurl/? id=doi:10.1021/bi00703a025 &redirect=false &format=unixref &pid=email@address.com
