When using the Library of Congress Classification online through the Classification Web, a yellow highlighted background on classification numbers indicates table modification records. It shows that the specific number or expansion is derived or modified from a classification table rather than being a standard whole number printed directly in the main text of the paper schedules.Key Details About Yellow Highlighting Table Modifications: Highlights values generated when a table is applied to a base number. Browser Feature: Appears primarily in specialized views like the Enhanced Classification Browser and Hierarchy Browser when calculating specific numbers. Distinction: Helps users differentiate standard schedule numbers from dynamic table-driven expansions. Table Modification RecordsNote: This section only applies to the Enhanced and Hierarchy browsers.When applying tables to classification numbers, there are cases when the entire table is not applicable and some of the table information is overridden. The overriding data comes from the area of classification which is applying the table. Whenever this happens, the table references will include the word modified. For example, in the previous screenshot, the record at HD9000-9019 contains the notice TABLE H18 modified.In this case, all of the lines from the caption Inspection (HD9000.9.A-.Z) onwards happen to be schedule records that override the records in Table H18 when that table is applied. If you click on Food supply. Produce trade, Table H18 is applied and the results are merged with the overriding schedules records, as follows:When Table H18 is applied to this area of the classification, calculated classification numbers are generated for the table records and those records would normally be integrated into the display. However, if any of the calculated classification numbers already exist in schedule records, they will not be displayed (they are overridden). When this happens, the overriding schedule records are displayed in yellow to indicate that these are modifications to the underlying table.See Also:Library of Congress ClassificationLibrary and Information Science Questions Answers QuizzesReferenceTable Modification Records

Table Modification Records

When applying tables to classification numbers, there are cases when the entire table is not applicable and some of the table information is overridden. The overriding data comes from the area of classification which is applying the table. Whenever this happens, the table references will include the word modified.
