opcit – Footnote-style bibliographical references

This pack­age ad­dresses the prob­lem of ex­press­ing ci­ta­tions in a style that is nat­u­ral for hu­man­i­ties stud­ies, yet does not in­ter­fere with the flow of text (as au­thor-year styles do).
The pack­age dif­fers from foot­bib in that it uses real foot­notes, po­ten­tially in the same se­ries as any of the doc­u­ment’s other foot­notes. Opcit also, as its name im­plies, avoids rep­e­ti­tion of full ci­ta­tions, achiev­ing this, to a large ex­tent, au­to­mat­i­cally.
