This document provides instructions for using the Alexandria Researcher program to search for and locate books in the library. It describes three ways to search - by author last name, by book title, or by subject. For each search type, it explains how to enter the search term and which box to click, and includes examples of what the results might look like. It also notes some key details to check in the results, such as whether a book is available, and how to narrow a search if too many titles are returned.
