Within the next two weeks some COMS 101 students may ask for help with a compulsory library exercise. There are 240 enrolled. The exercise was prepared by me, and I tried to make it clear enough for them to follow unaided, but some will probably need help anyway. It is designed to familiarise them with finding library resources beyond the course reading list, using the COMS portal, the catalogue, and on the level 4 and reference collection shelves. They have to find and cite a chapter in an edited book and a journal article, following the Harvard author-date style as linked on the COMS portal under Citation Guides.
