Library blocks help ensure that your students have quick, easy access to important information about the library, including links to our website and contact information for librarians. Because you create the library block from scratch, you're free to customize it with whatever information is most suitable for your students' needs.
To create a Library block in Moodle 2.7:
'Turn editing on', and go to 'Add a Block' (this option appears at the bottom of the right sidebar as the default)
Select 'HTML' from the dropdown menu
Select 'Configure (new HTML block) block' from the list of actions to begin adding content to your library block.
