An effective literature review is always built on the foundation of a high quality literature search, one that is comprehensive and systematic. And for any new project, a literature search is a crucial early step in the research process.

Finding literature on a question is usually easy; finding the right literature, and all of the most relevant literature for a solid literature review, is harder.

Through explanatory notes and practical, step-by-step guidance, we've designed this guide to help you understand how to effectively plan and carry out your literature searches.

Feedback from the community

Your Guide is simply superb.  Many thanks for a great resource which I will be promoting with advanced stage degree students in food science agriculture and veterinary medicine here in UCD.  It is the best guide I have come across in some time so many thanks for this "Toolkit".  This will be invaluable for UCD -Students, those new to research, and those who need a refresher in literature searching.

I found helpful information in the literature search guide which helped me to find many food science articles relevant to my honours project.

The guide is also available to read on LibGuides in English, Chinese, Farsi and Italian language (more translations to come!). For librarians and faculty teaching information literacy skills, we also offer a free SCORM package for an online e-learning module which can be added to your own learning management system (LMS).
