Your reading lists are likely to include references to books, journals and web pages. Books listed will usually be available in print in the library. They may also be available electronically, in which case it will say "electronic resource" under the title in the reading list.

Your reading list may specify particular book chapters. If these chapters are available electronically, it will say "digitised chapter" on the list. Your lists are also likely to have references to journal articles. These are clearly marked as "article".
