Thomas G.L. Cockcroft’s Index To The Verse In Weird Tales (1960), free on Archive.org. Also related magazine titles edited by Farnsworth Wright, such as Oriental Stories and The Magic Carpet.

Many good scans of Weird Tales can now be had free on Archive.org, but this Index should help speed up the finding of ‘on the original page’ verse by your favourite authors. Since it’s also effectively a keyword index to likely header illustrations, it might also be used as an index for finding illustrations by theme.

Also, I wonder if it might be possible for an ambitious student typographer, seeking a project, to get in touch with the heirs of Thomas G.L. Cockcroft (1926-2013) and request permission to do a new properly typogrified, designed and printed version of this old stencil-duplicated Index To The Verse In Weird Tales. Perhaps the new edition might integrate the best of the poem illustrations in the public domain, and for each poem add a line of colour-coded keywords indicating theme and symbolism/setting?
