eresource

An eresource (often written e-resource) is a resource delivered electronically through a network and used primarily in library, information science, and educational contexts. E-resources include digital texts such as e-books and e-journals, online databases, streaming video and audio, software as a service, and datasets. They are designed for remote or on-site access and are commonly accessed via library catalogs, discovery systems, or dedicated platforms provided by vendors or publishers.

Access and management: E-resources are typically licensed rather than owned outright. Access is controlled by authentication methods such as IP-based access, proxy servers, or single sign-on; access may be restricted by license terms, geography, or user type. Libraries manage eresources through ILS or library management platforms, linking resolvers, and knowledge bases to help patrons locate content. Metadata and persistent identifiers (e.g., DOIs) aid discovery and linking.

Licensing and economics: E-resource procurement often uses subscriptions, bundles, or patron-driven acquisition. licensing terms define permitted uses, reproduction rights, and interlibrary loan, and they influence budget planning and renewals. Consortia may negotiate favorable terms.

Challenges and trends: Common issues include license complexity, access stability, link rot, digital preservation, accessibility for users with disabilities, and privacy concerns. The rise of open access and open repositories complements paid eresources, while libraries balance budgets and user needs.

Impact: E-resources broaden access, enable remote learning, and reduce physical storage needs, but require ongoing management of licenses, authentication, and technical platforms.
