An INSPEC Puzzle

I have a good puzzle for you. Can you find the article The everday world of work : Two approaches to the investigation of classification in context by Jacob (Journal of Documentation 57(1)) in the INSPEC database? I couldn't despite both Jake's and Ulrich's assurances that J DOC is completely indexed by INSPEC. Indeed, it appears that Jacob's article is the only one missing from INSPEC for J DOC 57(1). Is this some sort of conspiracy? Luckily, ERIC and ingenta contain the necessary information.
