I think one of the reasons we are seeing an uptick in the hyper-specific request is because in this time of uncertainty, a book rec is something people can have more control over. Even my family members are getting way more specific than normal. There are other reasons too, and the whys don't really matter, but dealing with the hyper-specific reader is not always about giving them the exact book they are asking for. Often it is more about listening to them and working together to find a suggestion.
I had remembered answering a question similar to the ones I have been receiving from all of you, so I dug through the archives and found this post from 2017. I have also reposted it in its entirety below.
I also have a few more posts tagged "serving difficult patrons" that you could access.
Finally, if you have an immediate RA Service related question, use the search box for the blog [top left corner]. There are over 3,000 posts here on the blog. I might have already answered your question. I never mind if you contact me, but I have been receiving more inquiries than normal, so I might not be able to get back to you fast enough.
