As informed during tour of Academia site of stack exchange, we can ask questions about actual problems faced in Life as a graduate student, postdoctoral researcher, university professor.
But some times we don't face problem but want to know about some topics, like
Where can we find impact factor of journals?
Why recently some books have their acknowledgement in the back as opposed the common practice of having acknowledgement in the front pages?
for which we don't find a dependable answer online.
So is it valid ask such questions on Academia site??
