Abstract

An item-providing system supplies items to a user device for consumption at the user device via communication infrastructure. The device may correspond to a book reader device or other type of device. The item-providing system uses a content delivery module to deliver the items to the user device.

Claims

1. A user device, comprising:

a device to-do list processing module configured to;

provide a request to an item-providing system to access at least one part of a list of entries maintained by the item-providing system, wherein at least one entry in said at least one part of the list provides an instruction for the user device to obtain an item;

receive said at least one part of the list of entries at the user device in response to the request;

provide another request to the item-providing system to obtain the item identified by the instruction;

receive the item in response to the other request; and

determine whether the received item is a duplicate of a previously received item, and if the received item is a duplicate, maintain a single record of the item.

2. A method for receiving an item at a user device from an item-providing system, comprising:

providing a request to an item-providing system to access at least one part of a list of entries maintained by the item-providing system, wherein at least one entry in said at least one part of list provides an instruction for the user device to obtain an item;

receiving said at least one part of the list of entries at the user device in response to the request;

providing another request to the item-providing system to obtain the item identified by the instruction;

receiving the item in response to the other request;

determining whether the received item is a duplicate of a previously received item; and

maintaining a single record of the item when the received item is a duplicate.

3. One or more non-transitory machine-readable storage media containing machine-readable instructions for implementing the method of claim 2.

4. One or more computing devices, comprising:

one or more processors; and

memory to store computer-executable instructions that, when executed by the one or more processors, perform the method of claim 2.
