To find books or eBooks in the library catalog, click "Advanced Search" to the right of the catalog search bar.
In the advanced search, type your research topic into the search term box. Then, select "Library Catalog", and set the "Material Type" to Books. Note that this will provide you with both print books and eBooks in your search results.
Once your search results load, you will have both print books and eBooks listed in your search results. To limit your catalog search to eBooks, look for the "Availability" limiter on the left side of the page under "Refine Your Results". Clicking on "Available Online" will limit your search results to eBooks which can be accessed online from any location. Note that you may be prompted to log in to your Atlas account again.
