Some tips for effective meetings with your librarian and thesis advisers:
* Bring a working bibliography with you. Even if you're not sure about many of the sources on there, it will give your adviser an idea of what work you are doing and what direction you are going in.
* If you're looking for a particular source you found cited somewhere else, show your librarian the original source you found the citation in.
* It helps to have an idea about the types of sources you are interested in finding. Is it data about phenomena over a period of time, or primary research about a topic, or examples of children's books on an environmental topic?
* Determine what sources may be easiest or hardest to obtain. What sources will be easier or harder to read and work with and how?
