As I am preparing for a research consultation, I had a random thought that it pays off as a librarian to be a reader as well. Especially so if you read books from your own library on various topics. I can then recall book options for students that may come in for a consultation.
For example, for the student writing on George Orwell, fascism, and the United States, Antifa (link to my review) comes to mind right away.
For the student writing on Black history and suppression of Black history in schools, Our history has always been contraband comes to mind (link to review).
I went to the library stacks, found them, and added them to the materials I would offer those students when they came in to meet with me.
By the way, this can also include articles I may have seen and read on a student topic that I can then share with a student. At times, I have sent a student a link to an article on their topic after a research consult in the hopes they will find it helpful.
I will note further that I have met librarians who, for whatever reason, declare that they do not read, or read as minimally as possible. For me, reading broadly helps me in my work. Even if it is just being aware and reading reviews as part of collection development can be helpful in helping students. But when I can put a book in their hands I have read and tell them that I have read it I think it has a bit more power. Now whether the student reads it or not, or at least skims it, is their choice. I am under no delusions they will read a whole book for a research assignment. All I can do is offer. Up to them to then use the resource or not.
As I am typing this, I am thinking of making the occasional list of books I have read from our library that I can recommend for certain topics. It could be an occasional blog post here in part for my own reference.
