Big data processing is a very powerful tool that has multiple applications: it can help designing marketing products, or take wiser decisions within the companies, etc.
According to ACRL, “librarians in all disciplines, in order to facilitate the research process, will need to be aware of how big data is used and where it can be found” (source).
But what about “small data”? Rufus Pollock defines it as “‘the amount of data you can conveniently store and process on a single machine, and in particular, a high-end laptop or server’.”
This excellent post at CILIP will show you how libraries can use this “local, distributed and context-rich” data to “create better user experiences and inform the development of new services and systems”.
