“Tell Us about Your Digital Archives Workstation”: A Survey and Case Study

Archival staff in the Manuscripts Division, Department of Rare Books and Special Collections (RBSC) at Princeton University Library lacked a fully-equipped digital processing workstation to capture, transfer, and secure born-digital and digitized archival content for long-term preservation and access. Staff recently conducted a survey that included information about the digital processing workstations of twenty institutions. The results of this survey informed a successful proposal to acquire a Forensic Recovery of Evidence Device (FRED) to serve as our digital processing workstation. The article will share details about the survey and considerations that went into our decision-making process, as well as introduce a collaborative tool to assist archivists in sharing specifications about their workstations across the field

Developing Policies, Procedures and Workflows for Stewarding Born Digital Collections in the University Library and University Archives at the University Of Illinois Urbana-Champaign

Broadly, electronic records are presenting libraries and archives with a new set of challenges. The goal of this project is to develop the first iteration of a set of policies, procedures, guidelines and workflows to address issues specific to stewardship and preservation of born digital materials held in at the University of Illinois Urbana-Champaign University Archives collections and establish a base of formal policies, procedures and workflows for the Preservation Unit’s Born Digital Content Preservation service staff to consult when assisting others with born digital Library collections materials. This paper outlines the project development, methodology and first iteration of documentation produced to meet this goal, and to begin coordinated efforts to steward born digital collections at the University of Illinois Urbana-Champaign’s University Library and University Archives.Ope

The Forensic Curator: Digital Forensics as a Solution to Addressing the Curatorial Challenges Posed by Personal Digital Archives

The growth of computing technology during the previous three decades has resulted in a large amount of content being created in digital form. As their creators retire or pass away, an increasing number of personal data collections, in the form of digital media and complete computer systems, are being offered to the academic institutional archive. For the digital curator or archivist, the handling and processing of such digital material represents a considerable challenge, requiring development of new processes and procedures. This paper outlines how digital forensic methods, developed by the law enforcement and legal community, may be applied by academic digital archives. It goes on to describe the strategic and practical decisions that should be made to introduce forensic methods within an existing curatorial infrastructure and how different techniques, such as forensic hashing, timeline analysis and data carving, may be used to collect information of a greater breadth and scope than may be gathered through manual activities

Convective response of a wall-mounted hot-film sensor in a shock tube

Shock tube experiments were performed in order to determine the response of a single hot-film element of a sensor array to transiently induced flow behind weak normal shock waves. The experiments attempt to isolate the response due only to the change in convective heat transfer at the hot-film surface mounted on the wall of the shock tube. The experiments are described, the results being correlated with transient boundary layer theory and compared with an independent set of experimental results. One of the findings indicates that the change in the air properties (temperature and pressure) precedes the air mass transport, causing an ambiguity in the sensor response to the development of the velocity boundary layer. Also, a transient, local heat transfer coefficient is formulated to be used as a forcing function in an hot-film instrument model and simulation which remains under investigation

Development of a preprototype times wastewater recovery subsystem

A three-man wastewater recovery preprototype subsystem using a hollow fiber membrane evaporator with a thermoelectric heat pump to provide efficient potable water recovery from wastewater on extended duration space flights was designed, fabricated, and tested at one-gravity. Low power, compactness and gravity insensitive operation are featured in this vacuum distillation subsystem. The tubular hollow fiber elements provide positive liquid/gas phase control with no moving parts, and provide structural integrity, improving on previous flat sheet membrane designs. A thermoelectric heat pump provides latent energy recovery. Application and integration of these key elements solved problems inherent in all previous reclamation subsystem designs

Capturing and Processing Born-Digital Files in the STOP AIDS Project Records: A Case Study

In September 2012, the Manuscripts Division of the Stanford University Libraries Department of Special Collections and University Archives completed a one-year National Historical Publications and Records Commission (NHPRC)-funded project to process the records of the STOP AIDS Project, an HIV prevention non-profit organization in San Francisco, California. This project marked the department’s first large-scale processing project to capture and process born-digital records. Building upon the nascent framework outlined by the AIMS white paper and the infrastructure developed by Stanford University Libraries, the project team captured born-digital records and implemented new processing strategies using digital forensics tools. This case study will document the strategies and workflows employed by the project team to capture and process the born-digital component of the STOP AIDS Project records. We will describe the successes, challenges and roadblocks encountered while forensically imaging 3.5 inch floppy disks, Zip disks, and CDs using Forensic Toolkit (FTK) Imager software. We will then outline our approach to processing nearly 30,000 unique digital files captured from the computer media using AccessData Forensic Toolkit (FTK) software, discuss our current delivery strategy, and offer some concluding thoughts
