The Revs Digital Library
The Revs Digital Library is a project within the Digital Library Systems and Services group whose goal is to ensure access and preservation of materials from the Revs Institute and the Revs Program at Stanford.
The Revs Institute in Naples, Florida is an independent educational organization that advances the scholarly study of automotive history. The Institute houses a library with over a million items, including a large and varied collection of automotive materials such as images, research books, ephemera, and specialized documents.
The Revs Program at Stanford was established to promote a new trans-disciplinary field connecting the past, present and future of the automobile. The program aims to put the automobile at the center of the university and raise the quality of academic discourse at Stanford and beyond. The program is now producing research data and generating course materials.
Working with Pixel Acuity, the Revs Institute is currently digitizing their collection of images using specialized digital cameras. Each slide, negative or print is cleaned and imaged at a high resolution. The images and associated metadata are collected and transferred to Stanford, where they are being accessioned into the Stanford Digital Repository (SDR) using an automated pipeline.
The automated pipeline is built using the Ruby programming language and relies on a "robot" framework, also developed at Stanford, for queing up and executing specific jobs in various workflows. For example, in order to be accessioned, each image must be analyzed to ensure its integrity has not been compromised in transit (by computing MD5 checksums), web friendly derivative images need to be created (JP2), images need to be moved to the digital "stacks" and preservation core, and so on. A "robot" is designed for each specific task, and tasks are organized into ordered workflows, with appropriate dependencies. Queues are established to automatically move objects through the pipeline, wtih additional servers running copies of the robots added as needed to maintain throughput.
The Revs Digital Library, currently under development, will ensure that all of the accessioned materials from the Revs Institute, as well as the original research from the Revs Program, are indexed, preserved and made available to library patrons, researchers and the general public. By digitizing materials and making them discoverable, content that was once available to a select few becomes useful and discoverable for a wide range of researchers. The Revs Digital Library is being built on top of the Stanford Digital Repository to provide a web based platform for discovery of automotive research and images. The Digital Library is developed in Ruby on Rails using open source technologies, including Blacklight, Hydra, and Fedora Commons and will allow for metadata editing, provide community features, and tools for researchers to further utilize the data.
As of October 4, nearly 68,000 images from the Revs Institute's collections have been digitized and staged on Stanford Library servers, with 1000 images accessionined into SDR. By the end of 2012, we expect to have all 68,000 images accessioned, with a digital library website for browsing and viewing the materials.
