It is generally preferable to use up-to-date source materials, ideally published within the last five years. However, what ‘up-to-date’ means in practice depends on your topic. If you are researching a topic that is changing rapidly, for example topics related to science, engineering and information technology, books and articles even a few years old may no longer be relevant.

seminal A seminal work is an important and influential work.

Sometimes, on the other hand, it may be acceptable or even necessary to refer to older source material, for example, if you are referring to a seminal work or if you are giving a historical overview of what scholars have said about your topic.
