What are the differences between lending models?

• Most similar to physical library books
• Can be borrowed by one user at a time
• Never expire from your digital collection

Metered Access (MA) titles expire from your digital collection after a certain amount of time or number of checkouts. You'll receive an email when a Metered Access title is about to expire, so you can repurchase it if you'd like.

There are four types of MA titles:

MA: by time (one user)

• Expire from your digital collection after a certain amount of time (e.g., 12 months)
• Can be borrowed by one user at a time

MA: by checkout (one user)

• Expire from your digital collection after a certain number of checkouts (e.g., 26 checkouts)
  Note: Renewals count toward the number of checkouts.
• Can be borrowed by one user at a time

MA: by checkout (concurrent users)

• Expire from your digital collection after a certain number of checkouts (e.g., 100 checkouts)
  Note: Renewals count toward the number of checkouts.
• Can be borrowed by multiple users at the same time
• In search results, title details pages, and Marketplace reports, the number of copies owned is the same as the number of checkouts remaining

MA: by earlier of checkouts or time (one user)

• Expire from your digital collection after a certain amount of time (e.g., two years) or checkouts (e.g., 52 checkouts), whichever comes first
  Note: Renewals count toward the number of checkouts.
• Can be borrowed by one user at a time

• Pay only when users borrow titles or get a pass to access a service
• Set a monthly target budget and user checkout limit to control spending
• Can be borrowed by an unlimited number of users at the same time (until your budget runs out)
• Can't be used for title assignments

• Can be borrowed by an unlimited number of users at the same time
• Expire after a certain amount of time (except Project Gutenberg titles, which never expire)
• Purchased as "plans" (where you select a set number of titles from a publisher's catalog for a flat fee)

You'll receive an email when a Simultaneous Use plan is about to expire, so you can renew it if you'd like.

Note: Some Libby and Sora Extras are available as subscriptions, which work similarly to Simultaneous Use titles. These services can be accessed by an unlimited number of users until your subscription ends.

Class Sets

• Available for schools and academic libraries
• Purchase the exact number of copies you need for a length of time (e.g., 3 months)
• Copies are automatically checked out to specified students on your selected start date
• Copies expire from your collection after your Class Set period ends
• Don't count toward user checkout limits

Many titles that are available as Class Sets are also available under the One Copy/One User lending model.

On-Demand Class Sets (ODCS)

• Available for schools only
• Similar to Class Sets, but don't need to be assigned to specific students
• Can be added to your general collection or used for content bundles or title assignments
• Copies expire from your collection once they're checked out and their lending period ends
• Don't count toward user checkout limits
