friends, yesterday iwent to french institute of pondicherry(pfi). they are doing a silent work of publishing the siva agamas. in fact this institute is recognised by UNESCO as a repository for siva agams. you can find most of the siva agamas here( of course in sanskrit ,french or english and not in tamil as such). i think apart from thiru-avadu-thurai this is the place one can find siva agamas. may be adyar library and institute of asian studies chennai to some extent. gandhi
