In some cases, you can copy, paste and print; however the allowable amount varies by publisher. Most of the e-books in EBSCO and eBook Central have a copy, paste and print allowance.
EBSCO:
If you are printing an eBook, up to 100 pages of a title can be printed per user in PDF format. In addition, you can select to save the pages as a PDF file instead of printing them. Availability of copy/paste functionality is determined by the publisher, and that information is presented in the Publisher Permissions information on the detailed record and in the eBook viewer.
eBook Central:
The default allowances are 40% for print and 20% for copy. Publishers may choose to modify these defaults on eBook Central, but typically they do not. eBook Central displays the patron's remaining copy and print allowances for each title when they are signed in.
Perlego:
You can copy and paste up to 10% of each book you’re reading – this limit is to prevent plagiarism and abide by copyright laws. Once you’ve reached your limit, Perlego will let you know. Please remember: you won’t be able to copy and paste any more text from the book once you’ve reached your limit and you can't remove any previous copies, so be mindful about which pieces of text are really important to you.
At the moment, the Perlego copy and paste feature is not available on Chrome for iOS devices.
