Be aware that publishers set daily limits on how much you can print or download.
Why is Ebook Central using EPUB as the default format?
EPUB is more accessible, especially for users with screen readers. It's reflowable, meaning the content adjusts to different screen sizes and devices.
Note: Page numbers may differ between EPUB and PDF. If you're citing or assigning page numbers, consider using the PDF format when available.
Can I still choose PDF instead of EPUB?
Yes! If a title supports both formats, you can select PDF during the download process or switch formats in the online reader.
