Dear Harry,

> 1) If any members have the *tāntrikābhidanakośa*, can they tell me if the
> word *saṁkita* occurs in it.  And if so can they scan the page for me.

To my knowledge, only three of five planned volumes have been published so far. The third volume comprises the words beginning with the letters ṭ-ph.

You can use the NWS ("Nachtragswörterbuch des Sanskrit"; a cumulative supplemental dictionary of Sanskrit) to find out whether a particular term is listed in TAK I-III.
