Aids to intellectual access

Type & granularity
Database with fields for author, title, uncontrolled subject terms, date, item identifier, and links to related transcribed text and page-image set. Each database record describes a single item as described in the microfilm inventory. For the letter-books, each letter is an item. All items have page-images. Not all letters are available as transcribed text.

The online presentation in American Memory does not use the SGML version of the The Writings of Washington directly. The SGML document was processed to extract each transcribed letter as a separate tagged record. These records are SGML-like, but not complete SGML document instances. The file of tagged records is merged with the database, indexed, and used to generate an HTML display on the fly.

Linking to digital reproductions
Database record contains identifier used in "directory name" for each metaobject representing a document. Naming system and page-turning dataset in place to link sequence and present page images. Filenames indicate page type, table of contents. Filename extension differentiates image types.
