Design Priorities in Digital Gateways: A Comparative Study of Authentication and Usability in Academic Library Alliances

Purpose: This study examines the design and functionality of university library login pages across academic alliances (IVY Plus, BTAA, JULAC, JVU) to identify how these interfaces align with institutional priorities and user needs. It explores consensus features, design variations, and emerging trends in authentication, usability, and security. Methodology: A multi-method approach was employed: screenshots and HTML files from 46 institutions were analyzed through categorization, statistical analysis, and comparative evaluation. Features were grouped into authentication mechanisms, usability, security/compliance, and library-specific elements. Findings: Core functionalities (e.g., ID/password, privacy policies) were consistent across alliances. Divergences emerged in feature emphasis: mature alliances (e.g., BTAA) prioritized resource accessibility with streamlined interfaces, while emerging consortia (e.g., JVU) emphasized cybersecurity (IP restrictions, third-party integrations). Usability features, particularly multilingual support, drove cross-alliance differences. The results highlighted regional and institutional influences, with older alliances favoring simplicity and newer ones adopting security-centric designs. Originality/Value: This is the first systematic comparison of login page designs across academic alliances, offering insights into how regional, technological, and institutional factors shape digital resource access. Findings inform best practices for balancing security, usability, and accessibility in library interfaces. **Keywords**: Academic library consortia, Login page design, User authentication, User experience, Security compliance.
