Abstract: This case study aims at describing how transformative agreements (TAs) have affected our profession with new tasks and workflows at two university libraries in Sweden, namely Karolinska Institutet University Library and Södertörn University Library. TAs are one of the mechanisms by which scientific publications are made open access; they involve moving libraries’ contracts with publishers from payment to read toward payment to publish. We will summarize the status and progress of open access in Sweden, in particular the significant growth of TAs over a short time span. We will then focus on describing how TAs have affected our everyday work and what new tasks they have imposed. We will share our experiences and point out things we find challenging, for example, we will explore questions about eligibility, the verification process, publication types and title changes during the contract period. We will also give some recommendations on how we would prefer the workflows surrounding the TAs to be. Finally, we will share our conclusions and comments about the impact of TAs on the publishing landscape and speculate about what will happen next.
