The Crossref Nominating Committee is inviting expressions of interest to join the Board of Directors of Crossref for the term starting in 2021. The committee will gather responses from those interested and create the slate of candidates that our membership will vote on in an election in September. Expressions of interest will be due Friday, June 19, 2020.
The role of the board at Crossref is to provide strategic and financial oversight of the organization, as well as guidance to the Executive Director and the staff leadership team, with the key responsibilities being:
After 20 years in operation, and as our system matures from experimental to foundational infrastructure, it’s time to review our documentation.
Having a solid core of education materials about the why and the how of Crossref is essential in making participation possible, easy, and equitable.
As our system has evolved, our membership has grown and diversified, and so have our tools - both for depositing metadata with Crossref, and for retrieving and making use of it.
To help better support the discovery, sale and analysis of books, Jennifer Kemp from Crossref and Mike Taylor from Digital Science, present seven reasons why publishers should collect chapter-level metadata.
Book publishers should have been in the best possible position to take advantage of the movement of scholarly publishing to the internet. After all, they have behind them an extraordinary legacy of creating and distributing data about books: the metadata that supports discovery, sales and analysis.
Hello, I’m Paul Davis and I’ve been part of the Crossref support team since May 2017. In that time I’ve become more adept as a DOI detective, helping our members work out whodunnit when it comes to submission errors.
If you have ever received one of our error messages after you have submitted metadata to us, you may know that some are helpful and others are, well, difficult to decode. I’m here to help you to become your own DOI detective.
A DOI (digital object identifier) is a persistent identifier attached to content (such as an article, chapter). It’s displayed as a link, and looks like this:
As you can see, it has several parts:
https://doi.org/ = the DOI resolver: makes the DOI a URL (actionable)
10.5555 = prefix: assigned by Crossref
YFRU1371 = suffix: decided and assigned by the member, should be opaque.
The prefix and suffix make a DOI, and with the DOI resolver form a DOI link.
As we mention above, the suffix should be opaque. An opaque identifier does not encode or describe any information about the work, such as publication name, date, or ISSN. It’s important to avoid encoding any human-readable information, so if any of the metadata associated with the DOI changes, there is no confusion between the information encoded in the DOI and that found in its metadata.
For example, 10.5555/njevzkkwu4i7g is opaque, but 10.5555/ogs.2016.59.1.1 encodes information which may change and therefore could be confusing or misleading in future.
The DOI link uses the DOI resolver to look up the registered URL for the item. This shows why it’s important to keep the metadata up-to-date, so that the DOI points to the correct URL for the item.
DOIs at different levels
A DOI may refer to a journal or book (a title-level DOI), or to a specific article or chapter.
Journals and DOIs
Like a set of nesting dolls, a journal may be made up of volumes, each containing a number of issues, each containing a number of articles. You can assign a DOI at each level, for example:
journal-level-DOI (sometimes called the title-level-DOI) 10.5555/QYPF2031. Like an ISSN, it refers to the whole journal
The role of the journal-level-DOI, volume-level-DOI, and issue-level-DOI is to link persistently to a point in the journal structure. These DOIs do not have any associated content, and it does not cost anything to register these DOIs.
However, article-level-DOIs do have associated content, and therefore a fee applies to register these DOIs.
Books and DOIs
Like a set of nesting dolls, a book may be made up of chapters. Again, you can assign a DOI at each level, for example:
book-level-DOI (sometimes called the title-level-DOI) 10.5555/ZAAR1365. Just like an ISBN, it refers to the whole book.
Both book-level-DOIs and chapter-level-DOIs have associated content, and therefore a fee applies to register these DOIs.
