Have you ever checked the profile of a site member here? (… and not just the ones who consistently make "WTF?!! :stars:" posts )
There are all sorts of peripheral factors that can help consideration of a book or article. Information about author's background can provide insight and/or context into their writing, which can aid
critical readers in more effectively judging the work. (critical, as in objective analysis and evaluation, not incessantly bitchin' ) The info may help understand the author's purpose in writing. Does the author have a track-record of strong bias, such that 'unhelpful' facts are routinely ignored to strengthen their argument? Despite apparently writing well in this instance, is the author competent in the subject (eg: see the clarifying comments on the government's fiscal system by
Good2Golf here )? Is there anything interesting, unusual, or significant in when and how they grew up? Is the particular school and/or professor's mentorship noteworthy in potentially affecting their writing? What else has the author written, and how received? Consider the audience of the author's writing. Are there any significant external events influencing the timing and context of the writing?
I find this background material can be even more helpful if you're not a SME (like me with fighter a/c acquisition -- which is also why I hesitate to post in topics where I don't really have a clue, but that's a separate rant). Otherwise, if you do a lot of reading in a particular field or subject, you begin to recognize 'trends.' For example, when I get a new book on one or two particular topics, one of the first things I do is check the author's bio (to help determine the stuff above); then look at the bibliography, which can suggest if the author is informed by a particular 'school of thought.'
All this to say, while my military career has been pretty high-speed, I can also be a thorough and discerning info geek (anything worth doing is worth doing to excess ;D ); considering the author is just another part of considering the publication.
It works for me.
