What is the purpose of an e-book with random verbatim abstracts pulled from journals?

I just found an abstract of mine, copied from a Journal, in an online book titled "Issues in Ecological Research and Application." It looks like this is a free book to download that just has random abstracts from various ecology journals. However, it appears like it doesn't take every single abstract from these journals. This company appears to also do this for many fields.

Actually, it is a bit stranger than full abstracts, it's basically full abstracts broken up with phrases like "journalists obtained a quote from researchers at University '..."

So my questions are, how does one get their abstract in a book like this? And what is the purpose of such a book? Abstracts are freely available online everywhere. Back in the print days, I could, perhaps, see the purpose of a library owning such a thing, but I can't quite understand what this is used for. Also is this even legal?
