Another thing; I seem to recall having read long ago that Invelos' title filter (on contribution) doesn't exactly match the Capitalization Tool that is found in the rules. Does anyone know if that actually is the case, and if so what the difference is?

Quoting ObiKen:

What about these word examples, they stay lower case using the Invelos capitalization tool:
• yet
• aka ("also known as" )

I actually realized "aka" when testing, but I would not have guessed "yet". Thanks for that!

I'm a little surprised that the capitalization tool capitalizes "From" and "With". There are a lot of titles in the database where those are not capitalized.

Quoting GSyren:

Quote:
(...) Here is what I am trying to do now (when updating ClipCapitalizer):

- Always capitalize the first and last word.
- Keep the following words in lower case (unless first or last):
a, an, and, as, at, but, by, for, in, nor, of, off, on, or, out, to, the, up, vs

Have I missed anything?

Looks great 
I can only see two words missing; 'so' and 'yet' (as mentioned by ObiKen).

Title capitalization seems to be used in English only.

It is a problem in capitalization tools, because it is so hard to detect what language a short string is in. I have tested a couple of language detection controls, but they are way too incorrect for this purpose.

I am working on a tool that will let you check all titles, original titles and rating details in your collection. It'll show incorrect results for non-English entries, but that's something we will have to live with (and ignore).

Here's a preview, showing incorrectly capitalized words:

Obviously "Geweld, angst" is German and should not be title capitalized, but what can I do? 
Checking locality and/or CoO is also too much hit-or-miss.

Anyway, for English I think I am close to the results that the title capitalization tool show. At least I haven't noticed any obvious mistakes. But it's really hard to be sure.

Also, the first word after a colon or dash must be capitalized even if it is otherwise in lower case.  E.g.:

Correct:    Star Trek 4: The Voyage Home
Incorrect:    Star Trek 4: the Voyage Home.

Yes, I'm handling colon. I hadn't thought of dash. Making a note of that. Thanks!

Edit: I think you meant hyphen rather than dash. It seems you can't use dash (en dash or em dash) in titles or rating details. We sometimes refer to a hyphen as a dash, but that is technically incorrect, afaik.

Sorry, forgot to comment on this before. I have added "so". Thanks for the heads up! 

I am now up to this:
a, aka, an, and, as, at, but, by, de, for, in, nor, of, off, on, or, out, so, to, the, up, vs, yet
All these have been verified in Invelos' capitalization tool.

If anyone can think of any other joining words that are missing, please let me know.

Here's others to add to the list:

out
per
pro
qua
via

I would also check whether the word is preceded by other characters, such as parenthesis or brackets, as this may result in the capitalization of the words before and after the character. If a comma precedes these special characters then it may only capitalise the following word. That is my observation, for what its worth.
