You can listen to the library's e-books and e-articles by using a screen reader. Celia's has instructions and examples of different listening and reading aids.
Adobe Acrobat Reader has features to help with accessibility, for example a text-to-speech tool. More information on Adobe's accessibility features.
Please note that not all e-books or e-articles are available for screen reader programs, for example pdfs that are saved as images. Check the individual pdfs to see if they can be used with a screen reader.
