As a former beginner myself, I recognize that the desire to produce EAD finding aids does not immediately result in their production. Among the members of CRRA, the more prosperous institutions can support computer systems that automatically generate EAD. But even these systems require an understanding of archival theory and how it might be maintained in a way congenial to machines. And other members of CRRA have the more difficult task of producing EAD without sophisticated equipment and IT support.
CRRA developed the EAD Template to help those who have no easy way to produce valid finding aids. While it tries to make EAD as easy as possible, beginners may still have bad luck with it. When I attended the Rare Book School EAD course at the University of Virginia in 1999, I had already produced hundreds of EAD finding aids. Daniel Pitti, the teacher of the course, offered helpful criticism and mentioned several mistaken ways of thinking that he had found among beginners. When CRRA members started using the EAD Template, I found one of these typical mistakes cropping up.
Archivists preserve filing systems that grow organically as routine activities generate records. The context of a document has evidential value; the whole filing system provides evidence about how an organization or individual conducted business, and therefore evidence of values, crises, attacks, defense mechanisms, unexpected events, daily life. Descriptions of such filing systems need to represent the organic form faithfully in all of its meaningful structure and peculiar quirkiness. Since filing systems generally have a hierarchical form, finding aids must also allow for components that contain other components that may contain other components -- boxes within boxes within boxes, or files within files within files.
Thanks to our familiarity with common filing systems on computers, we should have no trouble with this concept. Typically graphical displays of the contents of a hard drive show pictures of folders, and inside them other folders, and after a number of these eventually the individual computer files. One can generally also choose to view the same structure as an outline representing this structure in a slightly different way.
