OpenAsset allows you to quickly generate Contact Sheets that can be dowloaded as PDF files.
Click the 'Contact Sheet' button from the search results page or from the carousel.
Your 'Create Contact Sheet' page will open. On the right side, pick your page orientation, paper size, number of columns/rows, and what information you want included with each image. Then click the green 'Create and Download PDF Contact Sheet' button.
On the lower left you can save your settings so the next time you create a contact sheet, your document will already be configured.
