Students are expected to develop a collection of poetry on a theme. There are many resources available for this task.
Sometimes themed collections are published - use the subject search on the library catalogue and search for WAR POETRY, or LOVE POETRY.
Poetry anthologies are sometimes arranged by theme. Sometimes this will be indicated in the catalogue record. Use the TITLE/CONTENTS search in the library catalogue and type in your theme and the word POETRY - eg: WEATHER POETRY or POETRY ANIMAL?
The Internet has many poetry pages. Below are just a few to use to get started.
