Did you know the Stanford Media Preservation Lab (SMPL) has helped create an online wiki collecting and describing audio and video artifacts one might encounter in the course of reformatting legacy media? Check out our two year update on the Atlas on Indiana University's media preservation blog.
The discovery of a particular scanning defect called Bayer moiré, occured while creating image files at Stanford University Library's Map Scanning Lab and prompted a more focused study. The Bayer moiré defect affects the ability of software to lift features from maps digitally. An analysis of findings has supported developing a better understanding of color filter array technology and some of its associated quality issues: rationales for on-demand file remediation of affected image files, options for map imaging in the future, an effective and open-source approach for vectorization, performance improvements for producing and vectorizing raster images.
An article on this study, authored by Matt Pearson, G. Salim Mohammed, Renzo Sanchez-Silva and Patricia Carbajales, which includes additional quality control measures for imaging large maps and a refinement of the topo raster image specification is now published in the Fall 2013 issue of the Journal of Map & Geography Libraries: Advances in Geospatial Information, Collections & Archives, entitled "Stanford University Libraries Study: Topographical Map Vectorization and the Impact of Bayer Moiré Defect."

"The founding of Yung-yidish, the first Yiddish artistic avant-garde group in Poland, grew out of a meeting in 1918 between poet Moyshe Broderzon and a group of visual artists centered around Yitskhok Broyner, Yankl Adler, and Marek Szwarc. Eventually, the group included some 20-odd members including Yitsḥak Katzenelson, Yekhezkl-Moyshe Nayman, and Hershele, as well as younger people discovered by the group, such as the artist Henekh Bartshinski and the writers Elimelekh Shmulevitsh, Khayim Leyb Fuks, and Yisroel Shtern."
Stanford's set of Yung-Idish is part of the Ezra Lahad Collection, which was acquired by Roger Kohn for Stanford in 1998. The issues, on crumbling thin cardboard stock, were painstakingly conserved by the Stanford Libraries' professional conservators in 2012, prior to their digitization.
Back in the 1980s, five libraries -- including Stanford's -- undertook an effort to provide better user access to their sound recording collections. The result of this effort was a union catalog of pre-LP disc holdings that made it possible for users to find out what each of the five institutions actually owned.
In June and July, approximately 30,000, images representing nearly 14,000 items were accessioned into the Stanford Digital Repository (SDR). These materials include about 12,000 images from the Revs collection, 128 additional books from the Stephen J Gould collection, 43 Inspector General semiannual reports to congress, and a particularly prized volume of the Talmud.
This is a story about the power of word of mouth.
Professor Donald Emmerson from the Freeman Spogli Institute for International Studies found seven 5.25 floppy disks containing files created using WordPerfect 5.1 under MS DOS 3.3 in 1992 and 1993. Dave Sare at the Institute posted " Professor needs to convert old files SOLUTION" in the expert partners mailing list and thereafter we are connected.
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.
