Hi! I have been lurking in this thread, as is my wont! I’ve just been stretched a bit thin lately and haven’t felt up to scraping together a useful contribution. It’s super flattering to be summoned though, so I’ll do my best!
So… There’s a couple different things at issue here. Library ethics is, as pretty much any ethical field, an attempt to reconcile a number of different priorities and concerns in order to yield the greatest good.
One of these concerns is duty to taxpayers. A public library is a recipient of public funds and therefore has a duty to provide those services and make available those items that make the best use of those funds. That’s usually interpreted as a duty to do programming with the broadest possible appeal, and to provide access to materials that serve as many people as possible. Now, crucially, this doesn’t mean that every program and every item have to have maximum appeal! It’s why we stock mysteries and romance and horror, and why we stock dense historical tomes and Cliffs Notes and high school algebra texts. Many libraries are going to have a book club almost exclusively attended by older white patrons who want to talk about the newest NYT Best Sellers - that’s a demographic that already uses the library and encounters lots of programming. Ditto young children and new mothers. LGBTQ+ programming, programming aimed at English-Second-Language learners, etc… Yeah, that’s just expanding our offerings and reaching more people.
Another concern is representation of the community. A core value of librarianship (especially in collection development, the curation of materials) is that library collections should be reflective of the community. A library in a heavily Spanish-speaking area with lots of immigrants is going to have much larger Spanish language and learning-English collections than a library in a mostly-white, mostly-affluent area. This is a good thing! Programming is the same way. Not every area needs an anime club, and a library in a retirement village doesn’t need a teen-after-school-program. What’s important is that we don’t overlook a population just because they’re not super vocal, super visible. While we can do demographic research and say “yeah, our community is 98% white and almost entirely English-speaking, we don’t need Spanish-language programs and books in Tagalog,” we can’t just assume that there’s no queer people in our very rural red-state communities. Those people exist, and deserve to have library materials and programs that reflect their interests just as much as anyone else.
(An aside from the above, regarding targeted “minority” programming… It’s pretty uncommon that a program is envisioned with “diversity” as an explicit goal? It’s more likely that a program identifies a need in the community and attempts to meet it. Often this is the result of direct patron feedback. “We get lots of folks asking for a basic computer skills class.” “People are asking for more craft programs for kids.” And yes, I’ve seen “lots of our younger patrons are asking for an LGBTQ+ focused book club” or something like that.)
And finally, yes, there is a duty to neutrality. Libraries have a duty to provide the public the materials they want to read. In any major public library you will find a wide selection of viewpoints on the shelves - including materials most folks will find pretty abhorrent. A good librarian defends the presence of those materials, so long as they are seeing use and meeting a documented demand. With a very limited budget, I have never known a librarian to over-represent ‘minority’ viewpoints in collection development. Col. dev. librarians are very good at getting bang for buck, they buy materials they know their community will use.
Programming is a little different. The OP refers to what we call “passive” programming - book displays. These are usually seasonal or related to current events. Black History Month, Banned Book Week, Christmas, Easter, Ramadan, and yes, Pride Month. And yeah, they can be fraught. If a community is vehemently opposed to a Pride display, frankly speaking, it usually goes away. But keep in mind… There are still queer people in that community. Bullied, harried, driven into the closet, but they’re there. No such thing as an all-straight community. Racially pretty homogeneous, sure. Religiously, economically homogeneous, OK, such places exist. (Fewer than you think, but whatever.) But there’s queer folk everywhere. I’d like to think the library is for everyone, even those who have to hide part of who they are.
I feel like I went on a bit of a ramble there! If anyone’s got more specific questions I can definitely try to answer or give a perspective, this post was kind of an attempt to give two cents on a hundred-post-thread.
