STM-Online was a scholarly journal that during the period 1998-2013 was published in parallell with Svensk tidskrift för musikforskning. STM-online was a purely electronic publication, indexed in RILM and EBSCO:s Performing Arts Complete Database.
In 2014 STM-online merged with Svensk tidskrift för musikforskning, under the new, bilingual name Svensk tidskrift för musikforskning/Swedish Journal of Music Research (STM-SJM). STM-SJM applies a model of continuous publication, but the material is also collected in printed volumes on a yearly basis.
