    <div class="moz-cite-prefix">I'm the primary research editor for
      sign languages for Ethnologue, so let me add a couple comments.  <br>
      <br>
      We've held off making any fine-grained classification of sign
      languages into families because we prefer to let the consensus of
      the field sort things out before we say anything.  A while back,
      for example, someone urged us to subdivide "Deaf sign language"
      into something on the order of village and national sign
      languages, but there still is debate about whether that's a
      reasonable way to do things or not, so for now we're just keeping
      them together in one large group.<br>
      <br>
      With regards to the comments within entries about what I'll call
      for the moment "connections" between sign languages, we're taking
      a close look at a lot of those.  Some of those comments were
      inserted solely on the basis of some historical event (e.g.
      someone from one school visiting another one early in its
      history), without actually looking at the impact of that event on
      the language.  We're working on getting rid of those, or
      clarifying that the comment is only about historical contact. 
      Certainly, if anyone knows of comments that are inaccurate, please
      let me know.<br>
      <br>
      Even when there are "connections" between sign languages, it
      remains an open question whether to consider this an instance of
      genetic relationship or borrowing.  One of the challenges in this
      area is that when a sign language is transported from one country
      to another, there's a good chance that it will creolize with home
      sign or other systems already in the new country, and so it's not
      a clean case of ordinary genetic descent.  <br>
      <br>
      Finally, although Ethnologue lists the 137 sign languages that are
      in ISO 639-3, we've recently concluded that one of them most
      likely never existed: Yiddish Sign Language [yds].  If anyone has
      evidence that it really did exist as a separate language (and not
      a dialect of some other sign language with added Jewish
      vocabulary), please let me know.<br>
