Building the Digital Collection


The contents of the book The Rosaleen Moldenhauer Memorial: Music History from Primary Sources: A Guide to the Moldenhauer Archives (Washington, D.C.: Library of Congress, 2000) were delivered to the Library’s Digital Conversion Group staff as a series of Quark XPress documents and converted to Hyper Text Markup Language (HTML) using Extensis BeyondPress 4.0. The HTML documents were subsequently consolidated into one document per essay and reformatted with Macromedia Dreamweaver MX. Portable Document Format (PDF) files were then generated from the reformatted HTML using Adobe 6.0.

Portions of the book (Foreword, Acknowledgements, and Introduction) that were not available in Quark XPress were captured using PrimeOCR optical-character-recognition software, saved as HTML, and incorporated into the main body of text.

Approximately seventy-five percent of the inventory list could not be converted from Quark and was manually keyed into HTML.


During the initial phase of the production process (1997-99), Systems Integration Group, Inc. (SIG) of Lanham, Maryland, scanned items from the Moldenhauer Archives at the Library of Congress using Umax and Phase I scanners. Both 8 bits-per-pixel grayscale and 24 bits-per-pixel color images were scanned at 300 dpi. Images were delivered as one set each of uncompressed Tagged Image File Format (TIFF) images and JPEG File Interchange Format (JFIF) derivatives with an average compression ratio of 20:1 grayscale and 30:1 color.

During the second stage (2001-3), the ITS Digital Scan Center scanned additional Moldenhauer Archives materials from the Library of Congress using a Phase I–ZBE scan back with a Rodenstock 135 lens. Images were scanned at 300 dpi color and delivered as uncompressed TIFF images and JPEG derivatives with an average compression of 50:1.

Images of items from other repositories were delivered to the Library of Congress in a variety of formats, including photographic negatives and prints, microfilm, and photocopies. These were scanned by Digital Conversion Group staff using an Agfa Horizon Ultra flatbed scanner with FotoLook SA 2.09.2 scanning software at 300 dpi.
Images scanned from photocopies were converted to grayscale and enhanced in Photoshop 6.0. JPEG derivatives were created with Photoshop, resulting in an average compression ratio of 6-10:1.

GIF (Graphic Interchange Format) images used in the PDF presentation were generated from uncompressed TIFF images in Photoshop 6.0 and scaled to size.

Finding Aid

The Encoded Archival Description (EAD) finding aid was derived from the inventory list in The Rosaleen Moldenhauer Memorial. HTML pages from the initial text conversion were copied to a text file, which in turn was converted to XML (UTF-8) using UniRed software. The XML file was then filtered by a series of XSL stylesheets using SAXON parser before being transformed by another series of XSL stylesheets into EAD format.
