1. Determine a topic: Pick something that interests you and try to find an aspect that you can narrow down. This is a good time to use encyclopedias/reference sources (e.g., New Catholic Encyclopedia, Oxford Research Encyclopedias: Religion, Oxford Dictionary of the Christian Church, Gale Virtual Reference Library, CREDO Reference, Blackwell Reference), Google Scholar, Google, and even Wikipedia (look at the references for links to scholarly information).
2. Formulate a focused research question/thesis: neither too broad nor too narrow. This is tricky and will take practice. You can start by answering "who," "what," "why," "when," "where," and "how" questions. Set some parameters (e.g., dates, geographic location, demographic information), but be ready to change them. Here are some more strategies.
3. From your question, identify keywords, including synonyms and related concepts, and possible subject headings: You can search for standard subject headings here. Concept mapping can be helpful.
4. Identify possible types of useful information: scholarly articles, books, literature reviews, edicts of Roman emperors, Papal Encyclicals, primary sources (e.g., letters, diaries, first-hand accounts).
5. Make a list of sites and databases where you can find these types of information. The Catholic Studies Subject Guide is a good place to start. You can also do a general search in the library catalogue. This is a very important step.
6. Combine keywords, phrases, subject headings into search queries: Try many different searches and combinations of terms. Expect that it will take at least 10 different searches to get a good feel for what is out there.
7. Keep track of interesting articles! (see slide on Zotero below)
Phrase searching: most search engines allow for phrase searching. This means that you can search for whole phrases (e.g., "early church") instead of individual words (e.g., "early" + "church"). Just put the phrase you want to search in quotation marks (i.e., ""). This will help limit your results!

BOOLEAN OPERATORS!
These are words that cause search engines to modify how they search. Let's look at this diagram to get a better idea.
Persecut*
Christian*
A search for persecut* AND Christian* will find results that contain both terms and will exclude results that only have one of the two terms.
Persecut*
Christian*
A search for persecut* OR Christian* will find results that contain either of the search terms. This will generate more results. Handy for synonyms.
A search for persecut* NOT Christian* will find results that contain persecut* but do NOT contain Christian*. Use this sparingly and play around with it.
Persecut*
Christian*
There are plenty of Academic Libraries that use a version of the CRAAP test. My take was inspired by this particular one from Western University.
