Our journal now has an International Standard Serial Number (ISSN), assigned by the Library of Congress (by their National Serials Data Program):
ISSN: 1937-8912
At the same time, we are now members of CrossRef and have been assigned a DOI (digital object identifier) prefix:
The articles in our inaugural issue will now permanently be available via doi:10.3765/sp.0.1 and doi:10.3765/sp.0.2. If on the back-end the articles are moved around, these permanent identifiers will be unchanged and simply point to the new location of the articles. So, everyone should link to these articles (and all others that have a DOI, which is increasingly every scientific article published nowadays) via their DOI.
