Texas Tech seal images 

I note that you reverted my replacement of Image:TTU Seal.svg, Image:TTUS Seal.svg and Image:TTUHSC Seal.svg with Image:Texas Tech CoA.png in their respective articles.  The reason I replaced them was twofold:

First of all, it simply seems to me that, at least for the TTU and TTUHSC articles (not so sure about TTUS) the Coat of Arms would more accurately reflect the overall visual identity of the institutions in question; according to the visual identity guidelines at , "[t]he Official Seal and Signature are [...] reserved for use by the Office of the President of Texas Tech University and are used to represent the official business of the university", whereas the academic Coat of Arms is intended as a "unified identity for all academic entities within the Texas Tech University System".  Using the Coat of Arms instead of the seals in our articles would also seem to reduce the (admittedly small) chance of them being mistaken for official documents of the university, and complies with the advice (which, while we are not bound by it under fair use, it would seem courteous for use to follow) that "[t]he Official Seal and Official Signature may be used only for documents and publications that represent official business of Texas Tech University" and that "[d]ocuments that are not official and formal should use the appropriate Academic Signature" (i.e. the Coat of Arms).  It also allows us to use a single image for all the articles, not to mention, in my opinion at least, showing the interesting part of the logo more clearly without the distracting border and text around it.

The second, and more significant, reason for the replacement, however, was that, while I'd originally uploaded those SVG seal images in good faith, believing them to be acceptable with U.S. fair use law as well as our policies, upon further reflection I'm not longer as convinced of this as I was.  In particular, while there are reasons for arguing that the SVG versions are not too detailed to pass criterion 3(b), especially given that they're freely available from the TTU web site anyway, I now feel that, regardless of the acceptability of their absolute level of detail, they are nonetheless replaceable by less detailed bitmap images, and therefore fail the non-free content criterion 3(a).

Thus, I no longer believe those images are appropriate for Wikipedia, and do not want myself to be associated with them.  As their uploader, I have the right to delete them; the reason I chose to tag them as orphan instead of deleting them directly is that I wanted to keep them around for a while, in case someone did object to the change, and did not want others to end up tagging them (and warning me about it) while they were there.  That said, I still don't want them to stay around forever with my name in the upload log; if you want to, despite the issues I outlined above, you're free to reupload them (or bitmap versions of them) under a different title, thereby assuming the responsibility of asserting their compliance under our policies and U.S. law.  I no longer want that responsibility.

Oh, and regarding the use of the TTUHSC seal at Texas Tech University Health Sciences Center El Paso Campus, I'm pretty sure that blatantly violates our non-free content criterion 8.  It's not like that article really needs (either of) the images, anyway.  —
