I assume this is site related since it's about the database and, I guess, only the admin would know this. How many manga(only manga, not doujin or non-Japanese books) are currently listed on Manga update? I've gotten wildly differing results from MAL and ANN about it. One says almost 50,000 and one says almost 13,000, respectively. But what about MU?

And if this isn't the right spot for this question, instead of deleting/closing the subject, can you move it to the relevant location?

Estimated over 100k, if I did my math right.

As of posting this, there are 190324 series listed in MU; excluding everything but non-doujinshi, non-oneshot manga, approx 168k of those are manga. Pretty neat, if I counted everything correctly. (:

If you're going by the series ID number (as you seem to be), you have to remember that some series pages have been pulled over the years, either as duplicate entries or because they became part of a larger series and got merged (mostly oneshots grouped into collections). So that reduces the total number of series by some amount.

I don't know how many there are because they just show up as invalid ids. For example:
