LabsExplorer has recently published an updated review on electronic lab notebooks. The first review was published in 2017 (LINK) giving a comprehensive list including short summaries for a variety of applications.
In this updated review, the authors provide a ranking list which was established by using a score system based on five different criteria: user-friendliness, completeness, connectivity, price, and special points. The list contains 28 different ELNs and can potentially be used as the first guide when choosing an ELN (LINK).
