I have been surprised that there is no style fo the use of archival documents. I have been using Endnote X2/Windword 2007/XP now for quite a while and have to submit my Ph.D. thesis in a few weeks. Because it is a thesis in history there are many citations from archives. I have tried for months to manually adapt the mansucript template to the needs of my thesis but it just wont work. There is always a comma on the wrong place or some word to much. The thesis has to be in Chicago Style.
I would need:
Title, Collection Title, Box, Folder, Page, Library/Archive, City.
As in:
Letter from J. H. van Horn to George C. Marshall, May 16, 1938, George C. Marshall Papers, Box 4, Folder Vancouver Barracks Correspondence, General, 1936-1938, May 8-16, 1938, George C. Marshall Library, Lexington, Virginia.
Often fields are not filled so they have to disappear. Also Endnote cuts archival citations short when they appear again even though it should not do so. There is nothing to prevent it, however, but at least the shortened version should make sense.
Any help would be greatly appreciated.
Thank you for your quick reply. My current version is copied below. It is about the 10th unsatisfactory modification:
Title, Date, Collection Title, Box Volume/Storage Container, Folder Folio Number, Library/Archive, City, Pages.
It appears as:
Letter from Walter B. Smith to Lucian K. Truscott, December 15, 1943, Walter B. Smith Papers, Box 27, Folder 201 File, 1942-1943, Dwight D. Eisenhower Library, Abilene, Kansas.,
Note the comma at the end. It always shows up even though Endnote is supposed to clean that up automatically. If the field for FOLDER is not filled it nevertheless shows up in the citation. Sometimes there is only a comma and no period, depending on which fields are filled.
I have more then 1000 footnotes so I could not find a short citation so quickly.
I appreciate your help.
Leanne, I greatly appreciate your quick reply. Unfortunately, I have no idea what you are talking about. I am just a dumb historian. 
Do you want a page of my thesis attached?
Thank you.
Leanne, thanks again for your quick reply. Good job with your son. 
In accord with the manual I tried to rework the templates in EDIT/OUTPUT STYLES/ Chicago 15th A COPY/ FOOTNOTES/TEMPLATES and in BIBLIOGRAPHY/TEMPLATES. (Endnote X2 Manual, Chapter 16, p. 448ff)
Refernce type is as indicated in my initial post ‘manuscript’.
I havent looked in the Ref Type catalogue because I dont know what it is and because I have to use Chicago style for all my other footnotes anyway.
I put in a search for the filenames APA 5th.ens and APA15th.ens inclduing the hideen files but nothing came up.
I never thought it would be that complicated. I thought I would just need some help with the templates above. I nearly got it right there is just some kinks that have to be smoothed out.
