On a regular basis, we look at the download data of the OAPEN Library and where it comes from. While examining the data from January to August 2021, we focused on the usage originating from libraries and academic institutions. Happily, we found that more than 1,100 academic institutions and libraries have used the OAPEN Library.

Of course, we do not actively track individual users. Instead we use a more general approach: we look at the website from which the download from the OAPEN Library originated. How does that work? For instance, when someone in the library of the University of Leipzig clicks on the download link of a book in the OAPEN library, two things happen: first, the book is directly available on the computer that person is working on, and second, the OAPEN server notes the ‘return address’: We have no way of knowing who the person is that started the download, we just know the request originated from the Leipzig University Library. Furthermore, some organisations choose to suppress sending their ‘return address’, making them anonymous.

What is helpful to us, is the fact that aggregators such as ExLibris, EBSCO or SerialSolutions use a specific return address. Examples are “” – pointing to the library of the Western Sydney University – or “”– coming from the library of the Università di Bologna. And in this way, many academic libraries can also be identified from their web address. Some academic institutions only display their ‘general’ address.

As mentioned before, our analysis delivered over 1,100 – 1,121 to be exact – different addresses. The chart displays those addresses divided by type, and we see that many academic libraries not just rely on aggregators such as ExLibris, but also directly give access to the OAPEN Library through their catalogs. The metadata of the OAPEN Library is freely available under a CC0 license, and can be downloaded as a MARCXML file to ensure easy library integration.

Which libraries and institutions are the biggest users of the OAPEN Library according to this data? The most downloads come from MediaLibraryOnLine, the first Italian network of public, academic and scholastic libraries for digital lending; the Bodleian Library of the University of Oxford; and Universidad Peruana de Ciencas Aplicados.

We are happy to see that our collection is finding its way to libraries and academic institutions all over the world!
