Short, practical notes about changes that affect how students find and download material.
Legacy notice collection retired
The outdated 2019–2020 archive was removed from navigation so the library stays focused on syllabi, notes and question papers.
Downloads are open access
Account registration, checkout and purchase-history steps were removed. Available files now open directly from each subject page.
Navigation and legal pages rebuilt
A shared responsive navigation, global footer, updated legal pages and an audited contact form now run across the public site.
R23 coverage expanded to ten branches
AI & Machine Learning, Data Science, Cyber Security and Internet of Things joined the six core branch collections.
