In the past, you told us that the breakdown of publications in the introductory overview wasn't clear and sometimes ambiguous.

We worked on making that chart more useful for you and, therefore, added the reading status as the default breakdown. Publications are now classified into either

• free to read

• pay to read

• unknown (for those where we just don't know the reading modalities at the moment)

We hope you are as exited as we are that for example the the OA-fraction in literature related to "Carbon Neutrality" is increasing continuously!

Let us know whether other breakdowns are helpful to you as well.

A last side note: Yes, we have seen the time axis being hard to read at the moment and we are on it to fix that soon.
