<div class="">I believe loc has changed the API for the service slightly. Need to investigate further.</div>

<div class="">Hello All,</div>
<div class=""><br class="">
</div>
<div class="">We are on version 1.4.2 and we have had a user report that the subject heading plugin is not returning results for either LCNAF or LCSH (OCLC works, however). The user doesn’t receive any error messages when using the plugin, but tried typing
in known subject headings for the Library Of Congress and it’s still not returning results. I checked the Background jobs and logs and there are not error messages. I also went to the LOC website and all appears to be fine when searching subject headings
on their site. </div>

<div class="">Has anyone else experienced a similar issue? Can you point me in the right direction for resolving this issue? </div>
