"Review literature" or "Review the literature"?

It all depends where it sits in use in language, Ori. First, I wouldn't capitalize it unless it was being used as a title or heading.

If such was the case then I could see the first being used. If this was part of some text it seems that the literature under discussion, being under discussion and therefore specific would likely attract a 'the' but no capitals.

But again, CONTEXT CONTEXT CONTEXT.

absolutely

on invoices, I've seen the activity listed as "Literature Review".

In the body of reports, I usually see it in the past tense.

I am performing a review of the literature. I am reviewing the literature. I did a literature review.

That's a very fortuitous coincidence Contrex.

In your case, the literature has been specific.
