Overlap of Item IDs

[dodrarikaan]

It occurred to me that I've never asked (and I don't see any posts about it either). There are a finite number of numeric IDs for items added to the game, like 99 in total. What steps do people take when setting the numeric ID of their modded items to avoid overlapping with other mods? Do you just match against the mods you use personally? Is there a list somewhere of which IDs are available? Do you pick whatever and assume the user can adjust the files locally if there's a conflict?
