In the University Library Catalogue, you can search for a variety of research methodology sources including general sources, sources specific to Public Administration, Policy Sciences, other disciplines or sources about a specific research method.
The University Library has a Research Paper Planner that provides some guidelines regarding the amount of time to allocate to each step in the research process. A liaison librarian can also provide some Research Advice if you run into difficulties.
The advantage of an excel format log is that you can sort by various columns to 'collect' your research in a variety of ways.
