Svenska fornskriftsällskapet (SFS) has been publishing writings in Old Swedish and Latin from the Swedish Middle Ages for more than 150 years (since 1844). Unfortunately, some of SFS's most popular editions are now completely out of print. This causes considerable inconvenience to younger researchers (doctoral and undergraduate students) who have not previously been able to obtain them. This is particularly true of the textual editions and other publications on the Middle Ages that are constantly cited in scholarly discussions. These works need to be reprinted to meet the existing demand. This is primarily the case with the text editions and commentaries on ancient Swedish published by the Swedish Society of Medieval Studies after 1900.
