In many cases that's fine.
I wish there were widespread general consensus that every item in a "list of X" article should be individually referenced. A year or so ago I tried checking out such lists, particularly those of which it was asserted that a reference was not needed because "references can be found in the linked article," and my experience was this was usually not true.
That gave you an opportunity to add the references to the linked articles.
The reason why references are needed is that in many cases list inclusion involves a matter of judgement, and the judgement should be that of an authoritative third party, not that of Wikipedia editors.
A lot depends on the saus that you accord to "List" articles. I tend to treat them as a combination Index and To-do reference. Until standard practice in books requires references to the index of the book, I don't see why we should be so taken with ourselves as to require references there.
Some exceptions would still need to be made such as or lists where membership would be derogatory.
