A Story from the Research Trenches: Erasmus+ in Mannheim
As part of our blog series, “Stories from the Research Trenches,” we often invite researchers and colleagues to share their personal experiences. For this installment of the series, we are delighted to have our colleague André Davids from KU Leuven Library of Economics and Business share about his recent Erasmus+ stay at the University of Mannheim. André talks specifically about the opportunity to explore Optical Character Recognition (OCR) tools, a topic that Faculty of Arts researchers often seek advice about. Read about André’s experience learning about various OCR software options, his takeaways on how they do things at the University of Mannheim, and his impressions about the city itself.
Meanwhile, somewhere else: Erasmus+ in Mannheim
Hello, I am André, and in March 2023, as part of the Erasmus+ program, I spent five days at the University of Mannheim. Why did I choose Mannheim? In the context of my work at the Library of Economics and Business, where I am involved, among other things, with OCR (Optical Character Recognition), it quickly became clear after some online research that they are very actively engaged in that field there.
I was warmly received at the library by Stefan Weil, one of the most active current developers of the OCR software Tesseract. He told me a lot about the university and the city, but also introduced me to the world of Linux, Ubuntu, Debian. In addition, I was able to experiment with various OCR software (Tesseract, eScriptorium, Pero-OCR) and received more information about the OCR-D Project.
In Mannheim, they primarily work on the further development of open-source software. Additionally, they offer support to students and researchers in using this software. Once a month, they organize an open online OCR consultation hour in collaboration with the University of Heidelberg, where anyone can ask their OCR-related questions. The “clients” are mainly researchers, but also library staff from other universities.
Also interesting to mention: The library has a room, the ExpLAB, which is dedicated to brainstorming, Design Thinking, etc. This room is fully equipped for brainstorming sessions, but also has Eye-Tracking Stations, Virtual Reality glasses, etc., which can be used by both students and staff.
This Erasmus+ experience not only enriched my knowledge about OCR but also about the city and university. Although Mannheim is a well-known city, I didn’t know much about it myself. Due to its architecture, it was chosen by the Allies in 1940 as a place to experiment with air raids and complete city destruction. As a result, there wasn’t much left of the city after World War II, and it had to be rebuilt. After long debates, the Baroque Palace (Barockschloss) was also rebuilt. Luckily so, because in 1967, the University of Mannheim could establish itself there. This building, with its width of 450 meters, is the second-largest baroque palace in Europe, after Versailles (but – and this is important – it has one more window than Versailles).

Navigating the city was quite a challenge since the city center has no street names but has been divided into squares since the 17th century. The most striking street is the one in front of the university, the “Kurpfälzer Meile der Innovationen” (Palatinate Mile of Innovation), which has 42 bronze plaques on the ground honoring famous innovators such as Carl Benz (automobile), Karl von Drais (precursor to the bicycle), Werner von Siemens, and others. Maybe an idea for KU Leuven?
What stuck with me most in terms of their work culture is the Teams channel called “Mittagessen” (lunch). This is where colleagues arrange lunch plans. This is also how I met a colleague who, as a student, did Erasmus at KU Leuven. I still don’t fully understand their working hours. Apparently, they work 40 hours a week, but I was always the first one there and one of the last to leave… Maybe they calculate time differently there. Everywhere is different, but a lot is still familiar. I look back very positively on my trip to another library and can highly recommend it to everyone.
Also interesting to see is the university library’s introductory video:
