Reusing your own previous work without acknowledging that reuse can be self-plagiarism.
Answer
true
Explanation
### Why this is right
Self-plagiarism describes reusing one's own previous work without acknowledging the earlier use.
### The concept
Academic attribution is not limited to crediting other people. If previously submitted or published work is reused, readers may need to know that it is not new material. Acknowledging the reuse avoids presenting old work as entirely new.
### Remember
Your own earlier work can still require acknowledgement when reused.
