Looking at the difference between Dewey numbers for slavery: 306.362 vs. 326...

300 (Social Sciences) + 6 (Economic institutions) + .3 (Economic institutions) + .36 (Systems of labor) + .362 (Slavery)

306.362 - Class here slaves [formerly 305.567], interdisciplinary works on slave trade - For a specific aspect of the slave trade, see the aspect, e.g., economic aspects of slave trade 381.44.

300 (Social Sciences) + 20 (Political science - Politics and government) + 6 (Slavery and emancipation)

326 - Standard subdivisions are added for slavery and emancipation together, for slavery alone. Class interdisciplinary works on slavery in 306.362

The number in the DDC22 index for both "Slavery" and "Slaves" is 306.362, so perhaps this is the more general number used. And while 306 is labeled "economic institutions," it is described in the DDC manual as referring to "social institutions." 326 appears to be used for slavery with particular focus on the politics of slavery. A logically related topic is emancipation, which is assigned the number 326.8.
