Designrr was built to create ebooks and lead magnets from your blog or website. But you can expand your ebooks content by adding your voice to a handpicked, relevant collection of content snippets, gathered from a variety of sources, around a specific topic, that you publish and share with your readers.
For example you could create an ebook of a summary of the best posts on a topic from many sites and include examples from these site. However, keep in mind its best to always credit the original author with a link to the source. This is called curation.
Content curation is a technique where you can quote someone else's content or another company’s blog as long as you attribute the source. There are no strict rules, but ethically you should never take a whole post and normally you just just quote enough to make your argument.
In terms of copyright it comes under ‘fair use’ which says that its OK to quote or re-use other content as along as its fair. In other words don’t copy someones post and claim it as your own. The safest way to do this with ebooks is to curate paragraphs from different websites ensuring that you always link back to the original website.
And the last way to be totally safe is to create books from Creative Commons or Wikipedia.
