Leslie is Metadata Archivist for the University of Texas at Arlington Libraries. During all of 2015, she is devoting 50% of her time as supervising archivist for an NCPHR grant given to Special Collections for the encoding of 290 print finding aids. Upon completion of the EAD encoding, they will be available online through the Texas Archival Resources Online website (TARO).
During the summer of 2013, she served as the processing archivist for the Santa Fe Railroad Land Records. Applying MPLP concepts and with the help of one student worker, the records were organized into nearly 300 manuscript boxes and two dozen oversized boxes. In addition to the records, there are nearly 1200 maps which she compiled pertinent details into a searchable database.
In 2009, Leslie began her work with the University of Texas at Arlington Libraries Special Collections as Archivist for the Tejano Voices oral history project. From 2010 through early 2013, she served as UTA's Mapping the Southwest Archivist on a major digitization project for the University of North Texas Portal to Texas History. The project uploaded more than 5,000 digital images of the rare and unique maps from UTA's holdings onto the Portal website. Leslie was responsible for reviewing each map's research potential and creating full-level catalog records in OCLC and Voyager.
Leslie began her archival career in 1999 with the approach of the 75th anniversary of Methodist Hospitals of Dallas (MHD). There, she proposed and implemented a system-wide history project. As the MHD Archivist and Historian, she established and organized the Methodist Hospitals of Dallas Archives, a project which culminated in early 2002 with the creation of a permanent exhibit on the history of Methodist Hospitals of Dallas. While still in her role at MHD, she became Archivist for the Dallas Jewish Historical Society (DJHS) in October 2000, and from 2002-2006, she served concurrently as Archivist for the Dallas Holocaust Museum and for the DJHS. In both roles, she brought the archives up to professional standards and developed expanded collections policies to meet the mission of each organization.
