**5.4. Support from libraries**

Academic libraries are usually where contacts can be found within a scientific institution for issues related to publication data and bibliometric processes/indicators. Librarians' clean data, compile publication profiles, and collect data within the scope of evaluations. They are thus specialists for handling data, particularly data related to publications, user statistics, and stock management.

This is where altmetrics represent a connecting element as they illuminate the use of publications in social media. Thus it is plausible for libraries to be directly involved whenever the issue of altmetrics is addressed at an institution. This makes sense because librarians are in contact with many areas of a scientific institution and offer advice on using information products. Roemer and Borchardt [26] identified this central role of libraries and summarize: "[…] librarians serve as natural leaders when it comes to altmetrics […]" [26]. They argue that this is due to the resources and data knowledge of libraries as well as their central position as contact partners for various target groups [27, 28].
