<p class="MsoNormal">YUL is one of the largest sites using AS in production. Several of our peers are in earlier phases of implementation, although we are not without company. One example is BYU. They are not using the custom plugins YUL is, but they are indicating
some system performance standards are not being met, such as length of time to save a record. Our goal is to meet the requirements our special collection colleagues need to perform at their best. The complete solution may not arrive as quickly as we desire,
but this is a top priority for Library IT. I think it is important to note that while there is a sense of urgency to resolve the current situation, this issue illuminates the need for expertise and systems coordination for the lifespan of ArchivesSpace at
YUL.<o:p></o:p></p>
