Palace Marketplace offers libraries access to ebooks and audiobooks from more than 1,000 publishers, including Penguin Random House, Hachette, Harper Collins, Macmillan, Simon and Schuster, Amazon Publishing, and Audible, as well as hundreds of mid-sized and independent publishers. DPLA works closely with libraries and advocates on their behalf with publishers to offer licensing models that better fit the needs of libraries.

• These include 40 x 10 concurrent,
• unlimited one-at-a-time, and
• 5 concurrent loans at 1/4 the price.

Currently, titles from more than 25 publishers are available with multiple licensing models, giving libraries the flexibility to keep one copy perpetually on the virtual shelf while lending out multiple copies of in-demand titles simultaneously.  In addition, more than 30 publishers are offering unlimited simultaneous use licensing through BiblioLabs, including Capstone, Orca Book Publishers, Independent Authors Project collection, Triumph Books, Chicago Review Press, Dark Horse Comics, and many more.
