A library that grows with learning
Source & case catalog
Useful links, ready for the next learner. Your study history stays yours.
Opening the catalog…
Contribute a link
Check a public source or image case, then choose whether to add it. Only the link, publisher title, topic and access details are shared.
What does a check mean?
RadOS checks the public page, its topic and listed image access. It does not independently review the images or certify clinical accuracy. Publisher restrictions still apply; no articles or images are copied into this shared catalog.
Build as you study
Make good finds reusable
Let the catalog remember suitable public links you discover in future study sessions.
Optional. Your answers, notes, images, cards and review schedules stay private. Turning this off stops future contributions.
Each learner starts with their own history. Opening a catalog link marks it as familiar for you; it does not count as completed learning or schedule a review.
Ready to discover
Shared links
Study checks for a suitable, unseen catalog link first. It checks the page again before use and searches the web if needed.
