I think you guys are talking about two different papers, and their titles are quite similar (no idea who is the copycat). Here are the two:
Mahlberg, M. (in preparation). Corpus linguistics and English language teaching: bridging the gap between theory and practice.
Keck, C.M (2004). Corpus linguistics and language teaching research: bridging the gap. Language Teaching Research, 8: 83-109.
I believe that asan82 is looking for the latter one, which is actually a book review on the following four books:
