Module:Citation/CS1/Utilities
< Module:Citation | CS1
 | This Lua module is used on 119,000+ pages. To avoid major disruption and server load, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own module sandbox. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them. |
 | This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing. |
This page contains various functions and tables that are common to multiple of the various modules that make up Module:Citation/CS1.
These files comprise the module support for cs1|2 citation templates:
local u = {}
