Is there a documented number of how many have been discovered as of today?

The estimated order of magnitude for the total number of galaxies in our Universe is 10 to the power of 11, that is, 100 billion galaxies so to speak.
All galaxies formed after the Big Bang, from matter scattered around the Universe to become protogalaxies and then the galaxies we see today. I guess there are still protogalaxies converting into galaxies today but I haven't come across any figure I can provide you with.
Regarding the second part of your question, list of galaxies exist. Some of these galaxies have been observed visually, some as radiogalaxies and so on. Their overall documented number stands at over 500,000 galaxies as we speak.

Textbooks and scientific journals speak of estimates of there being 200 billion galaxies. There is nothing in this regard but speculation because the entire concept of the formation and growth of the universe has always been and remains to be guesswork. There is a lot to be seen , but most of it is very poorly understood. Now they are not going to come right out and announce this on FOX News. However the science journals are full of the various theories, arguments, speculations, rebuttals, name calling, revisions that you would normally find in religion. For instance, science cannot account for 90% of the matter they beileve is in the universe. So how can they make an accurate count of objects not seen ?

New telescope techniques are discovering more galaxies all the time.
Probably all galaxies at extreme distances don't exist anymore.
The most active formation era for galaxies has probably passed.
The universe has limits,to it's size and to it's longevity.
There are probably millions or maybe billions in existence right now,our milky way is one of them.
Spiral galaxies like ours or any others are probably in end stages in the evolution of our universe.
The elimination of galaxies at this time is probably greater than the production of new ones.

I'm not sure how many are documented but I'm under the impression that its to high for us to even count at this point.i believe the best way to describe it is time frames,=.using life as an example(human life)if your lucky and you are of perfect health and u live to be 100,lets just say...that is but a millionth of a second according to the age of our planet...well that might not be a good one.. OK....a cell is to our body as our Galaxy is to our universe

10^22.
No one knows how many galaxies are formed on a daily basis.

The odds are that there are many more than 130 billion galaxies in the universe.

So many we can't count them al. That is why it is crazy to think we are the only planet out of billions that has water and the right components to have life on them.

Having just taken astronomy in college - I know there are 88 galaxies that we can see -- and there are no others forming as of right now
