ARC Library separates book capacity from advanced Reader and Author tools.
Start with what you need
The Subscription page begins with your current plan, renewal state, book allowance, and the actions that apply to you. Paid members can edit billing, change plan, or cancel through the billing service that owns the subscription. Free members can review their access or browse upgrades.
Choose the sentence that best matches your goal: more book space, the complete Reader toolkit, ARC campaign tools, or both Reader and Author work. ARC Library recommends a plan from that answer, but it does not start checkout or hide the other choices.
Compare every core plan
Use the comparison below to check all five core choices against the same access questions. On smaller screens, each plan becomes a focused card with the same information.
Compare plans
ARC Library offers Free, Unlimited Tracking, Premium, Author Pro, and Combo. Open the live Subscription page for current prices and complete plan details.
The comparison in Subscription stays visible under the guided choice. Open Subscription and select View details or Details on a plan to see its complete feature and benefit list. Billing questions remain in Help instead of making the comparison longer.
The Subscription page shows current prices and the plans available on your platform. Web billing and mobile store billing use their respective checkout and management flows. On Android or iOS, Restore purchases reconnects an eligible store purchase to the signed-in account.
Unlimited Tracking is a monthly add-on. Its web checkout uses the monthly price shown on the plan card; choosing it never silently switches you to a yearly cadence.
Changing plans does not delete your Library. If access to a premium tool ends, its existing information remains yours even when the tool becomes unavailable.
