Shift-lab is a collective of five artists who expand their studio practices to collaborate on artist books and multiples. Shift-lab is Katie Baldwin (Huntsville, AL); Denise Bookwalter (Tallahassee, FL); Sarah Bryant (Tuscaloosa, AL); Macy Chadwick (Petaluma, CA); and Tricia Treacy (Boone, NC).

They have exhibited their work at Hamilton Wood Type & Printing Museum (Two Rivers, WI), Seager Gray Gallery (Mill Valley, CA) and San Francisco Center for the Book (San Francisco, CA). They have presented their creative research at the Philadelphia Art Book Fair and have participated in the Codex Book Fair since 2015. Their work is included in numerous collections including: Dartmouth College Special Collections, Rhode Island School of Design Special Collections, Yale University Art of the Book Collection, Jack Ginsberg Book Arts Collection and Mary Austin Book Arts Collection.

Since its founding in 2013, this collective has produced three major artist book projects as well as a number of smaller projects and printing events. Its most recent project REF (2019) investigates the transition from traditional reference texts in dedicated physical spaces toward the use of algorithmic relevance and keyword searches. Working together, members of the collective created fifteen responses to traditional reference texts using dates related to this transition as an organizational principle. The development of the project took place online, through contemporary technology such as Skype and Google docs, as well as in person in several locations and libraries across the United States.

These women members work from across the US to expand dialogue through exhibitions and projects that investigate narrative, communication and the book. Shift-lab continues to study the shift in contemporary perspectives relating to studio practice, collaboration, and both digital & analogue experiences.
