Where was Seshat worshiped at?

As far as I know, no single Temple of Seshat has been officially found. Seshat shared a Temple at Heliopolis I believe. Also, I heard Tahuti (Thoth) Preisthood subsumed Seshat's so it could be that any temple dedicated to Seshat were re-dedicated to Tahuti.

But since, She is the Goddess of Libraries She may been worshipped in Library. In Egyptian times, writing and the written Word were considered sacred. That would be my guess...
