In this paper, -4th line in the first paragraph on the (first) page 89,
then each full subcategory of $\cal H$ closed under limits ...
should or should not the word reflective be present:
then each full reflective subcategory of H closed under limits ... ?
I think that the word "reflective" is omitted by mistake, but I'm not sure.
It seems strange to me that if $\cal H$ is a locally presentable category then each full (but possibly non-reflective) subcategory of $\cal H$ closed under limits is closed under $\alpha$-filtered colimits for some regular cardinal $\alpha$.
