This book on group psychotherapy is a great resource for learning. To use it, simply start reading from the beginning to understand the theory and practice concepts. When handling the book, be gentle as the dust cover is a bit damaged. To maintain it, store it in a dry place away from direct sunlight to prevent further fading of the text block. Also, try to avoid getting it wet as the pages might get damaged. If you want to mark important points, use a bookmark instead of folding the pages to keep the book in good condition.
