A very useful and large collection of teaching and learning resources for UK Higher Education is the JISC-funded Jorum project, which is a growing repository of resources produced in UKHE, often by JISC-funded projects. Indeed, it's now a standard condition for JISC-funded projects that they deposit their outputs in Jorum.
A large proportion of the resources are released under reusable licences as Open Educational Resources (OER), and thus can be used by teaching colleagues, though you should always check the licence conditions of a resource for any conditions of use (eg attribution, no derivatives).
You can browse by subject, or search by keyword, title or author.
The experimental 'widget' below displays 50 resources in the category "Subjects allied to Medicine". You can also browse this topic on the Jorum website.
