Start with the index volumes using terms identified in background research.
Look up references to sections that appear to be relevant. Before reading any section’s text, check to see if there is added or amended text in either a pocket part or a separate pamphlet supplement next to the volume. There may also be a supplementary pamphlet at the end of the entire set.
Read the text of the statute carefully. Look at adjacent sections to see if they may be relevant as well. There may also be separate “definitions” sections that define terms.
Following the statute language, there may be references (annotations) to cases that have interpreted the section. Often, case annotations and references to secondary sources appear in pocket parts and supplements even if the text of the code section has not changed.
