And Steven, sorry for misspelling your name. It has been a long time.

1. It depends on your definition of “librar*”

2. I don’t actually track these things on an ongoing basis. I’ve mostly used two wikis as source material.

3. Given both those caveats, I’m fairly certain that, including only English-language blogs, there are more than 500 currently-active blogs by library people (and quite possibly more than 1,000, depending on your definition of “currently-active”), several hundred (at least 300, possibly more than 1,000) blogs from public libraries, a few hundred (at least 250, possibly many more) blogs from academic libraries.

So, yes, it’s fair to say there are more than 743 active “libr*” blogs.

I think all those numbers are defensible on the low end. On the high end? Could be off by an order of magnitude (if you allow very loose definition of “currently-active”), but I’d be surprised.

Using a moderate definition (“at least one post every other month and at least one post within the last two months”), I’d guess somewhere between 1,000 and 5,000 English-language “libr*” blogs–and, to be sure, at least hundreds more in other languages.
