This reference books collection is great. I can search for a term and see results from different reference books. In this case, I would like to check a few entries to find the best for my purpose. But once I go into an entry by clicking it, because I want further detail than the citation, I cannot come back to the list of results to see the other results. Is there a way to do so? Or do I have to start over the search again? Thank you in advance for advice!
