i have a greater range of science fiction and fantasy magazines, mostly in digest format, and series original anthologies, than i've as yet been able to make time to list; please e-mail me at v$imt$v at my sub-domain, i-m-t.demon.co.uk, with a list of your wants, and i will check this outpost of L-space for any & all of them that are currently visible or get-able-at for you.
indications of interest in as-yet unlisted magazines & series [& non-series] anthologies will also increase the likelihood of my listing them next.
