NOM
1,442 proceedings under this prefix, in the Board's own numbering. One row per number the Board opened directly; a sub-docket is listed on its own series’ sheet, which is what a row links to. A proceeding holding nothing is listed all the same — the Board opened it, and the number is the answer where the documents predate this record (coverage).
1,442 proceedings is more than one page should carry, so they are split by number above — each band is a permanent address covering 1,000 numbers, whatever the Board opens in it later.
