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.
Typically, when an editorially significant update is made to a document, the publisher will not modify the original document, but will instead issue a separate document (such as a correction or retraction notice) which explains the change. This separate document will have a different DOI from the document that it corrects and will there have different metadata.
In this example, article A (with the DOI 10.5555/12345678) is eventually retracted by a retraction notice RN (with the DOI 10.5555/24242424x). Each document has Crossmark metadata, but the fact that RN updates article A is only recorded in the RN’s Crossmark deposit. The Crossmark internal API has to tie the two documents together and indicate in metadata of the original document (A), that it has been updated_by the second document (RN).
Example 1: simple retraction
This is a simple example of article A being retracted by a retraction notice RN where both A and RN have Crossmark metadata deposited.
First, the PDF is produced and the XML deposited to Crossref.
This is a simple example of article B being corrected by a correction notice CN where both B and CN have Crossmark metadata deposited. The only real difference between this and the previous example is that we are creating a different kind of update.
When a member does not issue a separate update/correction/retraction notice and instead just makes the change to the document (without changing its DOI either), this is called an in-situ update. In-situ updates or corrections are not recommended because they tend to obscure the scholarly record. How do you tell what the differences are between what you downloaded and the update? How do you differentiate them when citing them (remember, we are only talking about “significant updates” here)? However, some members need to support in-situ updates, and this is how they can be supported.
Example 4: correction of article that has no Crossmark metadata deposited
If you deposit Crossmark metadata for a retraction or and update notice which, in turn, points at an article that does not have Crossmark metadata assigned to it, we will generate a “stub” Crossmark for the item being updated. The stub metadata will simply copy essential Crossmark metadata (crossmark_domains and domain_exclusive) from the updating metadata. This metadata can be queried via the Crossref API, but won’t activate anything on your site unless you add the Crossmark widget to the corresponding page of the item being updated.
Example 5: correction notice that corrected multiple documents
Sometimes members issue correction or clarification notices which provide corrections for multiple documents. This too can be supported by Crossmark. In the following example, one correction/clarification document provides updates to two documents (F and G)
