Guhanandanatha parampara perspective of subrahmanya?

[Dev]

Namaskaram,

Thank you for group access. 

My research and following generally relates to Sri Vidya Sadhana Peeth in Kashi, https://web.archive.org/web/20230406230155/http://shreevidyasadhanapeeth.com/ - they‘ve also many interesting publications available, as well as S.K Ramachandra Rao, who often worked nearby at kashi university nearby: https://profskr.com/. 

Both are a treasure trove of knowledge about Sri Vidya.

Currently, I find myself drawn, and have permission from guru to explore the Sri vidya interpretation of who many in the north call Kartikeya - as that knowledge of subrahmanya has mostly been lost in northern traditions. 

I’m especially interested the how Sri vidya relates to the idea of parabrahman in the form of subrahmanya.

I‘ve been researching for many weeks now, now looking in the Tamil traditions that S.K Ramachandra Rao was closely related to in the parampara of (Sri Guhanandanatha).

Although there‘s two books I can‘t find, even after many hours a day research over several weeks. 

They are ..

Ashreya Subrahmanya Stotram - Sri Subrahmanya Siddha Ashtottara Shatanamavali

By Sri Atmanandanatha & Compiled by Srimati R. Bhagirathi (Based on Lectures by Sri Goda Venkateswara SastrigaL)

& 

Subrahmanya Tattvam by Sri Chidanandhar

I believe they may be both out of print, which would be a tragedy to the knowledge within.

It‘s possible I‘ve looked everywhere. But I think they may be gone. 

Does anyone have knowledge of how to get those books, & links to the Guhanandanatha parampara perspective of subrahmanya? 

They don‘t appear on Giri trading or even on contacting many different previous publishers.

I promise to be of help to anyone looking for anything else, and to contribute to discussions where i can.
