. More specifically, over the last 3 months CORE had more than 25 million users, tripling our usage compared to 2017. According to
We also offer other services, such as the CORE Repositories Dashboard, CORE Publisher Connector and the CORE Recommender. We received great feedback with regards to the CORE Recommender, with George Macgregor, Institutional Repository Manager at Strathclyde University, reporting:
We are thrilled that this year CORE made it to the moon. Our next destination is Venus.
The CORE Team wishes you Merry Christmas and a Prosperous New Year!

The CORE service is working in partnership with ProQuest to deliver more content within their library discovery services (Ex Libris Primo and Ex Libris Summon). What does this mean for the end user? This means that search results will bring back more relevant content from OA repositories worldwide in addition to the existing library collection records. The user will not have to go to a separate search interface to run the same search query.
To celebrate this milestone, we gathered the knowledge of our data scientists, programmers, researchers, and designers to illustrate our portion of metadata and full text with a less traditional (sour apple) “pie chart”.
. It is a pleasure to see CORE listed as Number 1 resource in this list. CORE has been included in this list thanks to its large volume of open access and free of cost content, offering 66 million of bibliographic metadata records and 5 million of full-text research outputs. Our content originates from open access journals and repositories, both institutional and disciplinary and can be accessed via our
“In the last year, we have managed to scale up our harvesting process. This enabled us to significantly increase the amount of open access content we can offer to our users. With more and more open access content being made available by data providers, thanks to recent open access policies, CORE now also captures and provides access to a higher percentage of global research literature ”, says CORE’s founder, Dr Petr Knoth.
With 66 million metadata records and 5 million full-text, from 102 countries, in 52 different languages, CORE becomes now the world’s largest full-text open access aggregator. CORE embraces the vibrant collections of both institutional and disciplinary repositories, while its large volume of scholarly outputs ranges from scientific research papers, to grey literature and from Master’s to Doctoral thesis. In addition, it is a metasearch for the all the open access peer-reviewed scientific journal articles published in open access journals.
There was also progress with regards to our services; the number of our API users was almost doubled in 2016, we have now about 200 registered CORE Dashboard users, and this past October we released a new version of our recommender and updated our dataset.
Around this time of the year, the joyful Christmas spirit of the CORE team increases along with our numbers. Thus, we decided to recalculate how far are the CORE research outputs – if we had printed them – from reaching the moon (last year we made it to 1/3 of the way).
We are thrilled to see that this year we got CORE even closer to the moon! We would also like to thank all our data providers, who have helped us reaching this goal.
Merry Christmas from the CORE Team!

It is intended for (possibly computationally intensive) data analysis. Here you can read the dataset description and the download page. If you need fresh data, and your requirements are not computationally intensive, you can also use our API.
Users can retrieve from CORE,
- 25,363,829 metadata records and
- 2,954,141 open access full-text records,
from 689 repositories (institutional and subject) and 5,488 open access journals. In addition, 122 users have access to the CORE API.
In the playful Christmas spirit we attempted this time to have some fun with the statistics.
Since we harvest outputs in other languages than English, we created a top 20 list of the languages that appear in CORE’s full-text manuscripts.
We also investigated how much we have progressed in the amount of the harvested metadata.
And the amount of full-text we have in our collection.
You may have noticed that the numbers in the graphs do not exactly match the numbers presented above. This is due to many reasons; for example during the harvesting process CORE retrieves either records with different types of inconsistencies or duplicates that we do not count in the “official” CORE collection. In addition, the numbers in the graphs include the amount of deleted or disabled records by the source repository. Therefore, the graphs illustrate the numbers that we actually harvest in CORE (what we have in our database), while the records that we provide via our search engine have been filtered and thus they are a bit smaller.
Finally, we calculated where CORE’s collection would take us if we had printed all the full-text from our database in a A3 page. We discovered that all this paper would take us 1/3 of the way to the moon.
Our next mission is to collect more full-text, enough to take us to the moon!
