Disable "more like this"

[rezseeker]

The suggested "like this" content is irrelevant and distracting

I tried the following code, but it's not working for me. Is the formatting wrong or is there some other way to disable "more like this" 

I'd be happy if at least it did not reference cross-library content? I've been looking through the interface and see no other way. I tried adding tags to the metadata of different libraries, but that got me nowhere either. Thanks

#similarCollapsible {
  display: none;
}

It looks like adding metadata at the library level at least limited the scope of suggestions after all. It just didn't kick in right away

"More like this" recommendations are based off the genre tags of all items.
