An independent study of scientific metadata collections has recently highlighted the quality of our publishing services. We cannot do better than quote the spontaneous communication we recently received from Dr Habermann:

I am a "metadata guy" in Boulder, Colorado and have recently been working to characterize scientific metadata collections in many repositories around the world. I recently took a look at the CrossRef Participation Reports and implemented a simple quantitative measure of completeness of these collections and a simple plot that compares completeness over time. I am using this approach to try to understand evolution of CrossRef metadata through time. As part of this work I looked at completeness as a function of collections size. The original dataset was a sample from CrossRef. I recently updated the sample to include all CrossRef members.

I am happy to let you know that SciPost has the most complete metadata of all 8670 CrossRef members with current collections of journal articles.

The attached Figure shows the data and you can see that SciPost clearly stands out. […]

Great work,

Ted

We are very grateful for this very interesting and rewarding piece of information, which, besides confirming the top-quality of our services, interestingly points to many aspects of metadata systems (ours and those of others) which can still be improved.
