Giving students a complete set of study resources
It sounds helpful, not detrimental. NB, whatever materials you curate and provide will never be "complete" by any objective standard. Consider a textbook: it may be written to address a particular course design, and focus on the main topics relevant to that course, but it cannot make other study resources useless.

The major factor here is how much work you want to put into creating those resources, not what their easy availability would do to impressionable students.
