To facilitate the process of inventorying the complete BRIT specimen collection, BRIT developed a web-based application called the BRIT Rapid Inventory of Specimen Collections (BRISC). BRISC is open source software that allows herbarium staff and volunteers to use tablets or laptops to count and record the contents of herbarium cabinets. BRIT began the inventory on 17 February 2015 with the combined efforts of staff and volunteers. Maintaining the established rate of inventory suggests BRIT’s estimated 1.01 million specimens will be completed after investing 210 person-days. In addition to obtaining an accurate account of BRIT’s collections, this project will also produce open source software (to be released soon) that can be used by other herbaria and biocollections for their own inventories.
