How do I search new titles
You will find a direct link to new titles here. Another route is to click on the Explore tab at the top of OPL's main page and select whatever format you are interested in. That will take you to a page featuring new titles, titles on order, and a couple of curated staff lists. Finally, if you are already in the catalog, you can always filter your search results by the left-side menu, which includes filters for New at the Library and (further down) Published Date.
I hope this helps!
