Digitizing the Sound Recordings

The sound recordings presented in the online collection were taken from the original seven-inch reel-to-reel tape recordings in the Library's collections. The analog audio from the tapes was transferred to Digital Audio Tape (DAT) to produce a master source for digitization. Some background noise may be apparent on the recordings. The audio files have not been digitally enhanced or altered in any way from their original state. WAVE, RealAudio, and MP3 versions have been supplied for each recording.

The WAVE files were created from the DAT tape at a sampling rate of 22,050 samples per second, 16-bit word length, and a single (mono) channel. The RealAudio and MP3 files were derived from the WAVE files by digital processing. The RealAudio files were created for users who have at least a 14.4 modem.

Digitizing the Photographs

JJT, Inc., of Austin, Texas, the Library's pictorial image contractor, produced the digital images in this collection in 1999. The company uses a digital camera manufactured in Germany and enhanced with JJT's custom software.

An uncompressed archival or master file was produced for each photograph, as well as three derivative files. The level of resolution employed for the Library's archival pictorial-image files is now ranging from 3000-by-2000 pixels to 5000-by-4000 pixels, depending on the types of original materials.

Cataloging the Collection

Quilts and Quiltmaking in America comprises selections from two collections housed at the American Folklife Center at the Library of Congress: the Blue Ridge Parkway Folklife Project Collection and the Lands' End All-American Quilt Contest Collection. The two collections' item level documentation differs. Because of this disparity, their materials have been described and indexed at different levels of detail.
