Compact cassettes, despite their simplicity, often present problems during digitization. This entry will highlight an approach to digitizing compact cassettes that exhibit squealing and speed instability after being rehoused using new hubs, slip sheets and associated components. Since I have started here the only cassettes, to present this problem are labeled “Stanford Bookstore”, so the actual manufacturer of the cassettes is unknown. Currently there are two common treatments for addressing squealing cassettes: playback in a cold environment or lubrication of the tape during playback. This entry describes tape lubrication and is informed by the work of Richard Hess and Marie O’Connell. I will first introduce the collection currently being digitized then briefly highlight an approach to applying D5 (Decamethylcyclopentasiloxane) lubricant to rehoused cassettes. For more information on D5 and soft binder syndrome, visit Richard Hess’s webpage here: http://bit.ly/11SBTVP.
The Manuscripts Division is please to announce two recent hires: Christy Smith and Joe Geller. Both have been long time soft-funded staff members at the library.
The University Archives is pleased to announe that it has added several items to the Stanford Digital Repository (SDR) recently. Included amongst the treasures are a variety of University maps and motion pictures, as well as faculty papers. Highlights include:
- Leland Stanford Junior University insurance maps (pictured here)
- Stanford University video collection
- Stanford University film collection
- George Forsythe papers
- David Starr Jordan papers
- Paul Ehrlich papers
To-date, over 160 University Archives collections have been added to SDR via self-deposit.
The Stanford Media Preservation Lab (SMPL) – the unit responsible for digitization and preservation of Stanford University Libraries' (SUL) extensive holdings of sound recordings and moving images -- is busy this summer preparing for our new home at 425 Broadway in Redwood City. SMPL is one of several SUL divisions relocating from our current occupancies at 1450-1454 Page Mill Road at the behest of the University.
Over 50 pieces of film, audio, video playback and treatment equipment -- nearly 1 ton of gear -- plus the desks of SMPL's four staff will be moved over Labor Day weekend (August 31 – September 2, 2013). In preparation for the move, normal lab operations will begin to wind down in early August. The work to reconfigure, cable and re-install the equipment will take 2-4 weeks. We expect to resume regular levels of services and productivity by October 1.
Stanford University Libraries has provided digital access to large portions of the Musical Acoustics Research Library (MARL) making available important research papers from some of the most eminent acousticians of the 20th century. The MARL collection consisting of nearly 60 linear feet of materials is dedicated to the study of all aspects of musical acoustics.
The Digital Production Group recently finished digitization of the Musical Acoustics Research Library collection and the content is now online. This collection consists of independent archives or libraries assembled by distinguished groups or individuals in the field of musical acoustics research. MARL is comprised of the Catgut Acoustical Society Library, the Arthur H. Benade Archive, the John Backus Archive, and the John W. Coltman Archive.
Some of the acoustical knowledge in this research archive has been used by leading players and manufacturers to modify the production of instruments, and the design of concert halls and recording studios. The research covers not only wind instruments, but also room acoustics, and the interplay between acoustical physicas and the mechanisms of auditory processing . The collection consists of papers, photograhs, medua, digital materials, wood samples, clarinet mouth pieces, and lab equipment.

With the University Archives making more and more collections available online, I'd like to take the opportunity to highlight some of the novel ways in which these materials are being used by researchers. What follows is a recent report from Ed Feigenbaum, Kumagai Professor of Computer Science Emeritus, about how his papers in particular are yielding interesting connections:
The Stanford Media Preservation Lab recently completed reformatting the audio tapes contained in the Betty Grover Eisner papers, held by University Archives. Eisner was at the vanguard of using LSD and other psychedelic drugs in her psychotherapy research during the 1950s and 60s. The majority of the tapes document long, multi-hour therapy sessions, with patients on mind alterting substances. Because of the content, which is often sexually explicit, these tapes are restricted; those interested patrons who want to listen to these tapes should contact the University Archivist for more information. A handful of tapes do have worldwide access however, including this cassette of a talk Eisner gave at a UCLA psychology seminar exactly 42 years ago.
