I've created my own Star Trek
chronology with TOS, TAS and TMP as the primary sources with some written materiel as secondary sources. Anything post TMP (which doesn't add up to much) is considered only wherein it could be consistent with that previously established or could be fit in without contradicting what had already been established. I can dig up a copy for you if you like.
As fas as I'm considered (for myself) the refit Enterprise
and crew is essentially still out there exploring after the events of TMP.
