 This bibliography is mainly restricted to a selection of a few books which are of some importance for the three structuralistic programs. An extended ‘Bibliography of Structuralism’ connected to Sneed’s program appeared in Erkenntnis, Volume 44 (1994). Another recent volume of Erkenntnis (79(8), 2014) is devoted to new perspectives on structuralism. We will cite below a few articles of this volume and other articles that are of relevance for the present entry. Unfortunately, the central books of Ludwig (1978) and Scheibe (1997, 1999) are not yet translated into English, but see the recent Ludwig and Thurler (2006). For an introduction into the respective theories, English readers could consult chapter XIII of Ludwig (1987) and chapter V of Scheibe (2001).
