I'm a librarian who loves anime, manga, and reading a wide variety of genres.
I decided to try out BL's book release feature and then realized it might have been better to pick one with a closer release date. My hope is that I'll get a reminder when the book is about to come out, or a reminder on release day. Thing Explainer is one of those I can actually justify asking the library I work at to purchase (and I'm the liaison for most of the sciences, so it even fits my subject areas!). However, we don't tend to do preorders, so I need to remember to request it after it's out.
Sometimes book shopping is a part of my job, and that is awesome.
