There is already a post on A.SE about the InTechOpen platform, which is currently listed as a predatory open-access journal. That question is 3 years old and since then the platform has changed a lot, for instance a number of highly respected colleagues have published there (in my field in mathematics). Moreover, the only accepted answer in the aforementioned post is a short "no", which does not address any specific concerns.
In light of that, my question is this: Is it worth publishing a book chapter through InTechOpen?
- Many prominent researchers in my field have published there (*)
- The quality of the articles is high in general, the papers are enjoyable to read and have excellent content (at least in my field)
- It is a great opportunity to summarize the current state-of-the-art research in a specific area, knowing that InTechOpen publishes all books open access and you can even find hardcover editions in libraries/bookstores
- The publishing fee for a single 20-page chapter is $1500, way too much (this is why it's considered predatory)
- I receive unsolicited mail from InTechOpen, inviting me to publish there, which is a big red flag for me
However, in light of (*) and the huge visibility that it offers (thousands of views each week), I am considering that it might be a price worth paying.
