Beth Brevick

Backstage Library Works

I’m a grandmother, but I’m not afraid to put on an inflatable T-Rex costume and run around the grocery store. I have a fascination with Punxsutawney Phil and love going on weekend trips to explore new places with my husband. And, though I’m a skeptic, I enjoy ghost hunting every once in a while. Cats > Dogs


Susan Falciani Maldonado

Muhlenberg College

Susan’s favorite thing is putting rare books and archival material into the hands of undergraduates and seeing what magic can happen. She is particularly interested in the use of college history as a lens through which students can examine historical events, culture, and society. Susan lives in NJ in a (finally!) renovated Victorian house with her husband and five cats.


Kristen Leipert

Bethlehem Area Public Library

Kristen works closely with the local history and reference collections and answers an assortment of patron questions on a daily basis. She spent 18 years as an archivist with a side of librarianship and is now a librarian with a side of archiving, but has always enjoyed the people part of each the most. In her spare time, she fetches snacks for her children but would rather be knitting.


Emily Marchello

National Museum of Industrial History

I care for the artifacts and help develop exhibits at the National Museum of Industrial History. When I’m not at work, I can be found on my small family farm riding horses, taking care of turkeys, or playing with our dogs.


Claire McRee

Allentown Art Museum

Claire is the associate curator at the Allentown Art Museum, where she especially enjoys working with the textile collection and brainstorming playful ways for visitors to interact with exhibitions. Outside of work, her interests include reading, trying new recipes, and indigo dyeing.
