Industrial Distribution of Representation Elections Held in Cases Closed, Fiscal Year 1981

p. 230. The stub heading carries a raised footnote marker ("Industrial group ^1"), but no footnote text is printed within this crop; the footnote presumably appears at the end of the table on a later page. The crop also ends just below the "Manufacturing" subtotal rule, so the nonmanufacturing portion of Table 16 continues on the following page. Arithmetic checks all pass: for every one of the 16 numeric columns the 22 industry rows sum exactly to the printed "Manufacturing" line, and in each row the AFL-CIO + Teamsters + other national + other local figures sum to the printed "Total" in both the elections-won block and the valid-votes-for-unions block. No suspected misprints. Scan quality is good; the only minor uncertainties are typographic, not numeric: the scan renders many dotted i's faintly (e.g. "in", "unions", "industries" in the headings and labels), and a few stray ink specks sit in the stub column beside "Printing, publishing, and allied products", "Chemicals and allied products", "Aircraft and parts" and "Ship and boat building and repairing" — these are leader-dot remnants/flyspecks, not footnote markers, and were dropped.

p. 231. The crop is a continuation page (running head "Appendix", page 219) and carries no printed column headings, so header_rows is empty. The grid has 17 columns: the stub plus 16 numeric columns, counted from the vertical rules and confirmed by the "Total, all industrial groups" line. Verification: I summed every one of the 16 numeric columns over the member rows of each of the three printed subtotal lines. Mining (4 member rows), "Transportation, communication, and other utilities" (6 member rows) and Services (14 member rows) all reconcile exactly in all 16 columns, which corroborates the digits and the column assignment for 24 of the 34 rows. The grand total cannot be checked here because the earlier industry divisions are printed on the preceding page. Scan quality: this is a degraded 1-bit scan in which small dots drop out (e.g. dotless "i" in "mining", "Oil"). Two labels were therefore restored to their evidently printed form rather than to the literal pixels: "U.S. Postal Service" (the periods are not legible on the image, which shows "U S Postal Service"), and in the footnote "Source:" and "Washington, D.C., 1972" (colon and first period not legible). The row label "Local and suburban transit and interurban highway passenger transportation" read to me as "surburban" at this resolution; I transcribed the standard SIC spelling "suburban" and flag it as the one doubtful spelling on the page. No numeric cell was doubtful. Structure worth noting for a reader of the grid: the block Construction / Wholesale trade / Retail trade / Finance, insurance, and real estate / U.S. Postal Service is set off by rules but carries no subtotal row on this page — each is its own division line. Trailing leader dots after "Metal mining", "Retail trade", "Communication", "Mining" and "Social services" were dropped as instructed; the isolated dots in the right margin beside "Mining and quarrying…", "Finance, insurance…" and "Motor freight…" are stray leader dots, not data. Nothing appears cut off by the crop.
