It would be interesting to find out what might be behind this sort if openness to Islam, in this case, or to any other religious group that might be promoted via public institutions, such as libraries.
I can see the logic behind a measure, especially in a library, that is supposed to host books and ides from all ways of life and from all cultures and ideologies. If we asume as a fact that muslims are being discriminated against and need support and people need to learn about them so that they stop demonizing them, then it may make sense to see this as an effort to lower the tensions, but it is probably more complicated than that.
If as a government you promote a religion, you would have to promote all religions. Of course, ideally governments should remain as far from religious activism or disputes as possible, but we know that in the same way governments can promote they can also intervene to stop certain religious groups from abusing others. In that sense, governments can't actually be separated from religion because sooner or later they have to make decisions that involve religions.
Being fair and balanced is the challenge and we know how difficult that can be whenever religion is involved
