Wondering how many issues in a series....

I've been looking at Daken comics, and X23. I'm looking around at different sights for the exact number of Daken comics, some say theres only 14, others 23, and one place said up to 90. And X23 I can't find Collision #2 anywhere.

Keep in mind that there are multiple series with the same name. For example, for X-23:

X-23: Innocence Lost

X-23: Target X

X-23: Oneshot

X-23: Ongoing (extremely short lived, unfortunately).

A good indicator is to compare the dates.

Well I've seen them say, 1st Series, 2nd series. Are these different stories?

Their is so many its hard to keep up.
