Call ya friends, call ya colleagues. Searching in HeinOnline just got even more intuitive.

Previously, HeinOnline users were able to perform a search either within a specific database or across all databases, with the ability to then filter databases one by one within search results. However, what if you know from the get-go that you’d like to search for a term in three, or four, or twenty different databases?

Now, thanks to wonderful suggestions from users Alina Kelly (Director of Research and Library Services, Mitchell Silberberg & Knupp LLP) and Jennifer Behrens (Associate Director for Administration & Scholarship, Duke Law School), you can. With a new feature, users can search multiple selected databases at once right from their HeinOnline welcome page. Watch the brief video below or keep reading to learn how to get started.

Let’s say you’re interested in learning more about presidential impeachment, and before you even enter HeinOnline, you know that you’ll probably find great information in our U.S. Presidential LibraryU.S. Presidential Impeachment Library, the U.S. Congressional Serial Set, and the Law Journal Library.

Navigate to the HeinOnline welcome page by logging in to HeinOnline. Users will see that the main search bar at the top of the page has been updated to include a button marked “All Databases.”

Want to update your keywords, but keep the search within those databases? Simply adjust your terms and re-enter the query to find that the search engine has remembered and maintained your database filters.

Want to add a Topic or other facet filter to your query, but, again, keep the search within those databases? Users can adjust their search as much as desired using the facets on the left-hand side, all while maintaining their previous database search criteria.
