When you're doing a structured literature search chances are you're using one of the main commercial scholarly search engines like Scopus, "Web of Science", or Google Scholar. These tools are often expensive, and often not intuitive to use. Unfortunately, you didn't have much of a choice in the past.

Recently free and open alternatives have been catching up with these juggernauts. Not just databases like OpenAlex or Crossref, but also structured search engines like Semantic Scholar or the topic of this post: The Lens.
