Abstract The number of scientific articles that need to be considered cover a research topic is ever‐increasing and quite difficult for newcomer assimilate. This particularly true in dynamic discipline like Molecular Magnetism. In order help young researchers this field, article proposes “review reviews” also known as an “umbrella review” on lanthanide‐based single‐molecule magnets ( 4 f ‐SMM). As preamble, various bibliographic search techniques AI‐based tools search, indexing, summarization are proposed commented.
