Yours seems to be an unpopular opinion. Perhaps you could partner with Bertrand Russell: <

I'm also reminded by an observation of the late Robert K. Merton, on latent vs. manifest functions. Originally coined in the context of sociology, but far more broadly applicable. In discussing these, Merton makes the perceptive observation that because latent functions are not immediately apparent, obvious, or significant, they represent a greater increment of knowledge and understanding than manifest functions, which are obvious, evident, easily understood and communicated, etc.
Popular works, or opinions, tend to be more accessible, yes. But they are also frequently a lower increment of knowledge or utility.
I too am pained by book and other information collections which pander to easy accessibility at a cost to insight and significance. That isn't to say that libraries should discount popularity at all, but I cringe when it seems to be the primary consideration.
By extension, other mass-context systems (markets, mass media, etc.) also tend toward minimum viable standards (often mis-stated as "least common denominator", problematic in several ways), and discount both long-term (non-obvious, non-apparent) benefits and costs.
