[Taxacom] Request for heritage literature

[Prathapan Divakaran]

Dear All,
I have been desperately trying for copies of the following historic papers
for quite some time. I have contacted many major libraries through
colleagues and all my efforts over an year have been unsuccessful. I would
highly appreciate help in getting the papers listed below. I am also
willing to purchase the same on payment basis.
Kind regards
Prathapan
