The issue of book recommendations has been raised before (to name a few examples); however, I'm raising it again because the problem doesn't seem to have gone away. books has over 2,500 questions, so I haven't had a chance to sort through them all. That being said, I've burned through almost 200 helpful flags to mark recommendation questions for closure, and I'm only on page 5/28. I think use of this tag should be heavily discouraged. Reasoning:
The vast majority of the questions in this tag are recommendation questions. Here are some examples of questions I personally flagged for closure.

Like I said, the majority of those questions came from only a few pages.
Several book recommendation questions are well-received by the community. Many of these questions do provide useful repositories are information, so I'm not suggesting that they be deleted by any means. I'm mainly referring to the questions linked to on the books tag itself.
There are other questions that are also book recommendation questions, but are not labeled with the tag. Since the questions that fall into this category have been closed, I don't believe the books tag adds any value. Adding it would just clutter up the tag more.
Situations where this tag could apply
Questions related to API's that deal with book information, e.g. this question. Although that example is not a good example of a question in general, more specific questions about book API's would be suitable, e.g. "I am trying to use the JQuery to get information for a library. However, I get when I use this code to access the API ." Etc.
Questions about a specific book exercise. Once again, however, I don't believe the [books] tag adds any value to these questions, so why use it? 1
Questions about specific differences between books, or better yet, different editions of the same book. If phrased correctly and specifically, these questions can be good contributions. 1
Other questions that are tangentially related to books or publishing, from a programming perspective, e.g. "I am trying to use JQuery to replicate the turning of book pages, but this code has a odd black border around the contents." That isn't the example question, but the example is the closest I could find that loosely represented this type of question in a quick search. 1
What can be done?
I've seen questions where users have suggested moving the questions to programmers.SE, but I'm not sure virtually any of these questions are a good fit for any SE site (because they're subjective, for example). I don't think this is a good option.
Since many of these questions are not being closed immediately, just relying on direct monitoring doesn't seem to have a high success rate. I only recently realised that SE already has a filter for subjective questions:
I don't know how long that has been around or how many such questions it actually discourages (before and after data would be interesting, at least to me). Is there a way to improve the message this filter sends?
My first idea was to delay the posting of questions that a filter considers highly subjective, but I wasn't sure if that would go against the principle of the site. Another potentially extreme idea that came to mind was hellbanning such questions for some time period so they don't show up to the normal community, but that seems... sneaky, perhaps. I don't want to add another category of questions or duties to the moderators' lists.
Thoughts?
TL;DR
The books tag has some valid uses. Questions about specific exercises in a book, specific differences between examples, and questions about API's that deal with book information are valid, in my opinion. The current influx of recommendation questions is not. There are quite a few questions in books that are great repositories of information for the community, and I'm not suggesting these be deleted. As it stands, however, the tag draws numerous recommendation questions that add little or no value.
Is there a better way to monitor this tag for the numerous recommendation questions that don't add any value or to improve the filter for subjective questions? Are there any other tricks that should work? Is the status quo acceptable and I should simply go outside and stop worrying about it? Should I ask a fourth question in this paragraph?
