OneSearch is a great place to look for eBooks at the library.
To search by keyword, brainstorm key concepts from your topic or question.
Example: "How do I teach my students how to read critically?"
Keywords might include: "critical reading" and instruction
To browse eBooks, search by keyword and refine your results to "full-text online" "books"
To browse eBook chapters, search by keyword and refine to "book chapters"
To search by title, type in the book title and see if it's available as an eBook. If it is, you will see a "full text availability" or "online access" link.
