The Illustrated Bartsch (TIB) is an extensive compendium of European master prints and commentary, published by the Abaris Books imprint of OPAL Publishing Corporation. Based on the 24 volume list, Le Peintre-Graveur, composed by Count Adam von Bartsch in the eighteenth century, the Bartsch has maintained its position as the premier reference work in the field of European master prints for over 40 years. The Illustrated Bartsch consists of images of European master prints from around 1400 until the arrival of the Industrial Revolution, around 1850. This 450-year span details the origins of printmaking, from entirely manually created and pulled prints, to the introduction of mechanical printing presses and photography.
The cooperation and contribution of many of the worlds finest art historians have helped the work maintain its relevance as an art reference manual by reflecting the ongoing progress of scholarship. The continual evolution of art history and scholarship provide new additions and attributions (as well as de-attributions), which have caused the project to grow exponentially. Bartsch's original 24 volume list has grown to over 100 volumes under the Abaris Books imprint, which was, in 2010, compiling further volumes.
Walter L. Strauss's General Plan for The Illustrated Bartsch was drawn up in the early 1970s, and the first edition of the collection (Netherlandish Artists) was published in 1978 under Strauss' own publishing company, Abaris Books. While an earlier attempt at producing an illustrated edition of Le Peintre-Graveur was abandoned after a single volume, TIB is now (as of 2010) in 104 volumes and growing. it is certainly the most intensive and complete effort made toward the project. After Strauss' death in 1988, Abaris Books was made an imprint of OPAL Publishing Corporation, which continues to produce volumes under his General Plan. Commentary volumes complete the catalogues raisonnés of artists named in Le Peintre-Graveur. Supplementary volumes present the collections of artists not indexed in the original list.
The first 48 volumes of The Illustrated Bartsch present every master print in Adam von Bartsch's Le Peintre-Graveur, and are referred to as “picture atlases.” Abaris Books coined this term in the General Plan to refer to the volumes which illustrate the original list of painter-engravers. While "picture atlases" are notable in their faithful presentation of Bartsch's list, time and scholasticism have ascertained accuracies and inaccuracies in the attributions made by Bartsch.
