+[Google Books](https://books.google.com) is Google's comprehensive book discovery and metadata service, providing access to millions of books from publishers, libraries, and digitized collections worldwide. The Google Books API enables programmatic search and retrieval of detailed book information including titles, authors, descriptions, ratings, and publication details.

+In Sim, the Google Books integration allows your agents to search for books and retrieve volume details as part of automated workflows. This enables use cases such as content research, reading list curation, bibliographic data enrichment, ISBN lookups, and knowledge gathering from published works. By connecting Sim with Google Books, your agents can discover and analyze book metadata, filter by availability or format, and incorporate literary references into their outputs—all without manual research.
