photo credit Summary You can use a new Crossref API to query all sorts of interesting things about who funded the research behind the content Crossref members publish. Background Back in May 2013 we launched Crossref’s FundRef service. It can be summarized like this: Crossref keeps and manages a canonical list of Funder Names (ephemeral) and associated identifiers (persistent). We encourage our members (or anybody, really- the list is available under A CC-Zero license waiver) to use this list for collecting information on who funded the research behind the content that our members publish.

[ Crossref Labs loves to be the last to jump on an internet trend, so what better than than to combine the Doge meme with altmetrics? Note: The API calls below have been superceeded with the development of the Event Data project. See the latest API documentation for equivalent functionality Want to know how many times a Crossref DOI is cited by the Wikipedia? http://det.labs.crossref.org.turing.library.northwestern.edu/works/doi/10.1371/journal.pone.0086859 Or how many times one has been mentioned in Europe PubMed Central?

The South Park movie , “Bigger, Longer & Uncut” has a DOI: a) https://doi-org.turing.library.northwestern.edu/10.5240/B1FA-0EEC-C316-3316-3A73-L So does the pornographic movie, “Young Sex Crazed Nurses”: b) https://doi-org.turing.library.northwestern.edu/10.5240/4CF3-57AB-2481-651D-D53D-Q And the following DOI points to a fake article on a “Google-Based Alien Detector”: c) https://doi-org.turing.library.northwestern.edu/10.6084/m9.figshare.93964 And the following DOI refers to an infamous fake article on literary theory: d) https://doi-org.turing.library.northwestern.edu/10.2307/466856 This scholarly article discusses the entirely fictitious Australian “Drop Bear”: e) https://doi-org.turing.library.northwestern.edu/10.1080/00049182.2012.731307 The following two DOIs point to the same article- the first DOI points to the final author version, and the second DOI points to the final published version:

You can now easily search for publications and add them to your ORCID profile in the new beta of Crossref Metadata Search (CRMDS). The user interface is pretty self-explanatory, but if you want to read about it before trying it, here is a summary of how it works. When you go to to CRMDS, you will see that there is now a small ORCID sign-in button on the top right-hand side of the screen.

We have just released a bunch of new functionality for Crossref Metadata Search. The tool now supports the following features: A completely new UI Faceted searches Copying of search results as formatted citations using CSL COinS, so that you can easily import results into Zotero and other document management tools An API, so that you can integrate Crossref Metadata Search into your own applications, plugins, etc. Basic OpenSearch support- so that you can integrate Crossref Metadata Search into your browser’s search bar.

If you’ve ever thought that scholarly citation practice was antediluvian and perverse- you should check-out patents some day. Over the past year of so Crossref has been working with Cambia and the The Lens to explore how we can better link scholarly literature to and from the patent literature. The first object of our collaboration was to attempt to link patents hosted on the new, beta version of The Lens to the Scholarly literature.

Last year Crossref and DataCite announced support for HTTP content negotiation for DOI names. Today, we are pleased to report further collaboration on the topic. We think it is very important that the two largest DOI Registration Agencies work together in order to provide metadata services to DOI names. The current implementation is documented in detail at http://citation.crosscite.org/ The documentation explains HTTP content negotiation as implemented by both Registration Agencies and provides a list of supported resource/content/record types.

PDF-EXTRACT

Crossref Labs is happy to announce the first public release of “pdf-extract” an open source set of tools and libraries for extracting citation references (and, eventually, other semantic metadata) from PDFs. We first demonstrated this tool to Crossref members at our annual meeting last year. See the pdf-extract labs page for a detailed introduction to this new set of tools.

If you are unable to download and install the tool, you can play with a experimental web interface called “Extracto.” Be warned, Extracto is running on very feeble server using an erratic and slow internet connection. The only guarantee that we can make about using it is that it will repeatedly fall over and annoy you. The weasel has spoken.

PHD Comics has posted its Valentine’s Day Reading list. Without DOIs!    So in order to preserve the scholarly citation record, we’ve resolved those that have DOIs…. Title:  The St. Valentine’s Day Frontal Passage Citation:  Sassen, K, 1980, ‘The St. Valentine’s Day Frontal Passage’, Bulletin of the American Meteorological Society, vol. 61, no. 2, p. 122. Crossref DOI:  https://doi-org.turing.library.northwestern.edu/10.1175/1520-0477(1980)061<0122:TSVDFP>2.0.CO;2 Title:  SUICIDE AND HOMICIDE ON ST. VALENTINE’S DAY Citation:  LESTER, D, 1990, ‘SUICIDE AND HOMICIDE ON ST.

Today two new record types were added to dx.doi.org resolution for Crossref DOIs. These allow anyone to retrieve DOI bibliographic metadata as formatted bibliographic entries. To perform the formatting we’re using the citation style language processor, citeproc-js which supports a shed load of citation styles and locales. In fact, all the styles and locales found in the CSL repositories, including many common styles such as bibtex, apa, ieee, harvard, vancouver and chicago are supported.
