There are two sets of tables - Bluepage Tables and normal whitepages tables.
The former pertains (as with anything in the bluepages) to court documents. BT1 provides myriad abbreviations for court terms, especially for memorandums and referring to the Record, or other internal court documents within litigation.
BT2 contains issues as imposed by specific courts and their court rules (either what abbreviation to use or which court rule contains the needed specifics).
BT2.3 has specific rules regarding U.S. territories.
The latter, the whitepage tables, refer to all the other non-bluepage rules (i.e. those not required to apply local practitioner-court rules).
Table 1 provides how to cite to cases, statutory compilations, session laws and administrative materials for the federal government and each state. Note, that a lot of how to cite to federal agency materials is located in Table 1.2. State materials T 1.3.
Tables 2, 3, 4, & 5 have foreign jurisdictions, intergovernmental organizations, treaty sources and arbitral reporters, which are becoming more cited over the years (and has expanded correspondingly).
Table 6 provides abbreviations for case names and institutional authors (important for citing to cases). Table 7 has court name abbreviations (important for indicating courts in case parentheticals). Table 8 has abbreviations for explanatory phrases. Table 9 for legislative documents. Table 10 has domestic and foreign abbreviations for geographical terms. Table 11 for judges and officials.
