Pokémon Adventures

How many volumes are there? I’m talking about the rereleased ones by Viz you can find at Barnes & Noble and the like. I have 1-4, but I could have sworn there were more

Here is the page on Bulbapedia about the books.
There are over 38 volumes, I’m not sure if they were all released in English but I’m sure they are as I have the older and some newer ones.
