Documentation of experiments is essential for best research practice and ensures scientific transparency and data integrity. Traditionally, the paper lab notebook (pLN) has been employed for documentation of experimental procedures, but over the course of the last decades, the introduction of electronic tools has changed the research landscape and the way that work is performed. Nowadays, almost all data acquisition, analysis, presentation and archiving are done with electronic tools. The use of electronic tools provides many new possibilities, as well as challenges, particularly with respect to documentation and data quality. One of the biggest hurdles is the management of data on different devices with a substantial amount of metadata. Transparency and integrity have to be ensured and must be reflected in documentation within LNs. With this in mind, electronic LNs (eLN) were introduced to make documentation of experiments more straightforward, with the development of enhanced functionality leading gradually to their more widespread use. This chapter gives a general overview of eLNs in the scientific environment with a focus on the advantages of supporting quality and transparency of the research. It provides guidance on adopting an eLN and gives an example on how to set up unique Study-IDs in labs in order to maintain and enhance best practices. Overall, the chapter highlights the central role of eLNs in supporting the documentation and reproducibility of experiments.
