Numbering in Citations
This subcategory of «Citations» is of interest only if you use a so-called numbered style as it is all about the numbering of citations.
The different options are:
|All References||Here you mark to have consecutive citations presented as a span rather than as a single number|
|Grouped References||In this route you can tick off if you want all the works that are quoted together with a common number. You can then specify which punctuation / word you want between them. Note that desired spaces must be set, although this can be difficult to see in this dialog|
|Use letters to separate grouped references||Check this box if it is desirable for each reference in a collection to be indicated by its own letter.
There is a sub-selection where you decide whether the letters should be lowercase or uppercase.
|In-text||Here you specify the format the numbering should have.
Select one of the four options from the list.
|Bibliography||Fill in «Precede by» and / or «Follow by» if you want any characters standing before / after the letters in the bibliography.|
