Which of the following is an advantage, rather than a limitation, of an e-library?

### Why this is right An e-library stores and provides resources electronically, so access does not depend on one physical copy being used by only one person at a time. When the resource and its access licence allow it, several users can read or download it simultaneously. That shared access is an advantage because it can reduce waiting for popular materials. ### The concept An **e-library** is a collection of digital resources, such as electronic books, journals, and databases, that users access through devices. Its benefits include convenient access and the possibility of serving multiple users at once, though the number of users may depend on the resource’s licence. Its limitations are conditions or costs that can make the service harder to provide or use. The options contrast a user benefit with expenses, technical dependencies, and legal restrictions. | Option type | What it means | |---|---| | Advantage | A feature that improves access or service, such as simultaneous use | | Limitation | A cost, dependency, or restriction that can hinder access | ### The other options - **A. High initial cost of hardware and software infrastructure**: this is a limitation, since setting up the equipment and programs can require substantial upfront spending. It is tempting because digital collections may save some later costs, but that does not remove the initial expense. - **B. Dependency on reliable internet connectivity and power supply**: this is a limitation because outages or weak connections can prevent users from reaching resources. It describes a technical requirement, not a benefit. - **D. Risk of digital copyright infringement and licensing restrictions**: this is a limitation because copyright rules and licence terms can restrict copying or access. Digital materials are easy to share, which makes this a relevant concern, not an advantage. ### Watch out Do not choose an option just because it describes something associated with e-libraries. Separate features that help users from costs, dependencies, or restrictions. ### Terms - **E-library**: Electronic library. A collection of books and other resources stored in digital form and accessed using devices. - **Hardware**: The physical equipment in a computer system, such as computers and storage devices. - **Software**: Programs that run on computers and provide functions, such as searching a digital catalogue. - **Infrastructure**: The equipment and systems needed to operate a service. - **Internet connectivity**: The ability of a device to connect to the internet. - **Digital copyright infringement**: Using or sharing digital material in a way that violates the creator’s or rights holder’s legal protections. - **Licensing restrictions**: Rules in an agreement that limit how a resource may be accessed or used. ### Remember A feature that lets more users access resources is an advantage; a cost, technical dependency, or legal restriction is a limitation.
