The Society of Scientific, Technical and Medical Publishers has openly released a document for publishing executives on institutional repositories. While this document clearly shows continuing resistance to public access through institutional repositories, and a fair bit of confusion, there are some positives here as well. One example is STM's open recognition of the value of the IR for public access, the feature of the first paragraph. To me, this is a bit of a milestone, not unlike when publishers first began to acknowledge the value of OA as a philosophical ideal. The open posting of the document, too, is a step forward. Let's hope that this is an initial sign that we're moving past some of the debate, towards a most welcome discussion of the issues.
