If you would like the library to confirm the number of users for a specific title, please contact Collection Services. Most titles allow unlimited access, but some expire after a certain number of uses or days.
| User Limit | Definition |
| 1 | 1 user at a time |
| 3 | 3 users at a time |
| Limited | 300 + uses per year and unlimited users at a time (sometimes referred to as non-linear lending) |
| Unlimited | Unlimited number of users |
| Concurrent | Up to an annual maximum of uses (typically 365 uses) to unlimited users. Once that number is met, the eBook becomes unavailable. |
| Nonlinear | The number of days used for each loan instance is subtracted from the total number of annual loan days set for the title - usually 325. For example, if four patrons each trigger a ten day loan for the same title, 40 days are deducted from the title's 325 loan days. Loan days renew on anniversary of purchase. |
