Highly recommended for scholarly research on any topic
What do you like best?
It gives access to the articles (inserted pdf) from very basic to very technical terminologies. I am still surprised why it's not very much popular. Those who like using google scholar may also consider Knovel. This will definitely save your time in research.
What do you dislike?
It should support search using wild cards (Boolean Algebra principle). Likewise, there should be asking question feature too.
Recommendations to others considering the product:
It should start asking questions feature as we have it on researchgate. This way, this tool can be really popular among researcher as well.
What problems are you solving with the product? What benefits have you realized?
I am a scientist and I have to search scientific literature many time a day. So, I use Knovel and it is really helpful for me.
