While often at the Stanford Media Preservation Lab we work with sound recordings Stanford acquired long ago sometimes we have the opportunity to work on media freshly acquired on the premise of immediately serving faculty and students. Recently a case like this occurred.

"We would like to provide high resolution images of brain slices for the research community to view. Would the [Stanford] Digital Repository be able to host our image data for this purpose?"
Have you ever had a similar question about how to make your research data available for other people to access? The Stanford Digital Repository is a great place to share research data of all kinds, including imagery.
The Stanford Media Preservation Lab has kicked around the idea of building a dedicated Digital Audio Tape (DAT) "ripping" workstation around a Digital Data Storage (DDS) drive for a few years, but we never pursued it in earnest. We assumed the benefits of using a computer drive to read audio DATs largely centered around extraction time and reporting. Transferring a DAT in a conventional deck is done in real-time, whereas a DDS drive, we were told, would rougly cut the time in half depending on the speed of the drive (Peter Oleksik's retrospective on the Fugazi archive mentioned speeds up to 4x real-time using the DDS method with a Sony SDT-9000 drive and DATXtract). We also liked the idea of accompanying logs identifying where dropouts occurred. Still, we were skeptical whether such a system would be better than one designed around multiple conventional decks. Was there a way to test both methods without investing a bunch of money in late 1990s computer components?
The Archive of Recorded Sound (ARS) recently took an active role in two courses during the spring semester, one in the Stanford Music Department and the other in the Program in Writing and Rhetoric, to encourage students to deposit their final projects into the Stanford Digital Repository (SDR). The purpose of working with these courses was primarily to introduce students to the SDR and its many benefits, and to walk them through the process of using the SDR's self-deposit tool. This instruction was backed up by customized online screencasts that guided students through the deposit process for the particular sets of materials within their projects. The rate of deposit for both courses was extremely high as the professors in each case elected to make the deposit of final projects into the SDR a mandatory part of the courses' requirements.
These new collections take advantage of recently released functionality that provides researchers with new rich discovery and access capabilities for finding and working with digital collection content. Researchers may now discover the following materials:
This collection provides supplemental data and spreadsheets related to the M.S. thesis in the Department of Geological and Environmental Sciences by Daniel Ibarra (December, 2014) and the subsequent publication in the Geological Society of America Bulletin (Ibarra et al., 2014).

It is no longer a surprise how ancient lakes in the western US -- such as Lake Surprise -- managed to become so large. Research undertaken by Daniel Ibarra, a graduate student working at the time with Kate Maher, assistant professor of geological and environmental sciences, showed that the root cause was a lower rate of evaporation than we see today.
SDR Deposit of the Week: Lizard Biogeography, Ant Populations, Mammalian Nervous Systems, and much more
Starting with the Class of 2014, the Department of Biology is depositing undergraduate senior honors theses in the Stanford Digital Repository (SDR). In May and June, 49 students deposited theses in the department’s Senior Honors Theses Collection.
