Major progress on AV media accessioning

March 29, 2020

TL;DR: The Stanford Media Preservation Lab (SMPL) and the Stanford Digital Repository (SDR) have together reached a major milestone with over half a petabyte of preserved AV media content accessioned in the repository. This summer, SMPL expects to complete working through the backlog of digital audio and video files accumulated over the past decade.

SDR Deposit of the Month: Crocodile constraints

Lots of interesting research is deposited into the Stanford Digital Repository every month, but when the research is about crocodiles, you know we have to know more!

While there are at least 26 species of crocodiles around today, many more forms of crocodiles have existed over the past 250 million years. Extinct crocodiles include those that were both much larger and much smaller than those living today.

SDR Deposit of the Week: Tunable properties of graphene

It's likely not news to you that Stanford researchers are undertaking all manner of cutting-edge and groundbreaking work. Applied Physics graduate student Aaron Sharpe is one such researcher who has become intrigued by a single-atom-thick layer of carbon called graphene that he says has, "continuously shaken up the field of condensed matter physics." Graphene sheets, as well as stacks of these sheets, show "unique and tunable electronic properties." We see why Aaron couldn't resist! We talked to Aaron about the research he and his colleagues have been undertaking with graphene and that has recently been published in Science.

Outreach by Stanford science librarians led Aaron to the Stanford Digital Repository (SDR), which he used to make the data and code for this publication publicly-available. "We chose the SDR because it was an easy process to make our data publicly available and permanent and to obtain a digital object identifier (DOI) to reference it in our publication." We completely agree with Aaron's comment that "with any publication, it is important that the data be publicly available."

Andrew Berger joins Stanford Libraries as Repository Manager

Digital Library Systems and Services is happy to welcome Andrew Berger to our staff in the role of Repository Manager. His first day with Stanford Libraries is July 22, 2019. 

In this role, Andrew will build on his recent experience at the Computer History Museum in Mountain View, where he served for five years as Senior Digital Archivist responsible for managing the museum's digital repository and for coordinating the museum's digital preservation activities across the content life-cycle, from initial acquisition to long-term preservation and public access.

SDR Deposit of the Week: Rocks and sustainable energy

When you think about rocks, you might not think about energy, but Christopher Zahasky does. Chris has been looking at vesicular basaltic volcanic rocks, like the one shown below, and the way fluid flows through them (see the graphical abstract for his recent article above). "These volcanic rocks are an important source of geothermal energy and provide a potential location for large-scale subsurface carbon dioxide storage for greenhouse gas emissions mitigation," Chris told us. "Understanding fluid flow is important for more effectively using these types of geologic systems for sustainable energy resource development."
