<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">There are publishers that, instead of using an actual endpoint URL as the URL registered w/ CrossRef, use what is essentially their own link resolver. I’ve seen this so far with two publishers, one is Elsevier
and unfortunately the other doesn’t come to mind. What’s interesting about Elsevier is they will actually take into account your session and send you to ScienceDirect, or, in the case of titles on an imprint with its own platform, that imprint’s platform,
depending on whether you have an institutional affiliation. So for example:<o:p></o:p></span></p>

DOI to an OpenAthens redirector prefix doesn’t work properly (to be resolved in “the latter part of 2025”).<o:p></o:p></span></p>

</div>
<div>
<p><span style="font-family:"Verdana",sans-serif">Sometimes you end up with the two sites for the same journals when a journal is hosted on a platform, but then for whatever reason, the publisher decides to host it on their own platform either additionally
or while ending current access on the platform.</span><o:p></o:p></p>
</div>
<div>
<p><span style="font-family:"Verdana",sans-serif">However, if the publisher made a deal with the platform for them to host content and sell it with perpetual access rights then you still have access on the host site.
</span><o:p></o:p></p>
</div>
<div>
<p><span style="font-family:"Verdana",sans-serif"> </span><o:p></o:p></p>
</div>
<div>
<p><span style="font-family:"Verdana",sans-serif">So, for example if Journal of the Association of ABC Science didn't have the ability to host it on the Association website, they might make a deal with Science Direct to host the journal and allowed them to
sell perpetual access rights to the consumer. In this scenario SD is acting as a hosting platform rather than Elsevier being the publisher.
</span><o:p></o:p></p>
</div>
<div>
<p><span style="font-family:"Verdana",sans-serif"> </span><o:p></o:p></p>
</div>
<div>
<p><span style="font-family:"Verdana",sans-serif">Then a decade later the Association website goes through an overhaul and they can host the journal themselves now. They canceled the SD contract, but since when they made the content originally, SD was allowed
to sell it with par it stays on the SD platform for those years for those who purchased access through SD retain access to those years as they paid for those years with a contract that included perpetual access.</span><o:p></o:p></p>

<div>
<p><span style="font-family:"Verdana",sans-serif"> </span><o:p></o:p></p>
</div>
<div>
<p><span style="font-family:"Verdana",sans-serif">A DOI is a persistent identifier, but it does not specify a single URL, so it is possible the DOI may point to either or sometimes both places. If it points to both, there is usually a screen that comes up asking
you to choose the platform - which confuses patrons, because they don't know which platform the library has the full-text with.
</span><o:p></o:p></p>
</div>
<div>
<p><span style="font-family:"Verdana",sans-serif"> </span><o:p></o:p></p>
</div>
<div>
<p><span style="font-family:"Verdana",sans-serif">And in some cases a journal could simply switch publishers for whatever reason, but again if the previous publisher was able to keep access to the years they published it then the DOI might show for that old
publisher.</span><o:p></o:p></p>
