Would you mind your Beta Reader being with other authors?

[Rhythm]

I'm a newer Beta Reader. (Only on my second book of beta reading) I adore it. But I have a question as I have gotten multiple offers from authors wanting me to beta read. (I've accepted 3 of them and have 2 more authors asking me about it.)
I was wondering for the authors out there.
Would you mind one of your betas being a beta for other authors also?
I mean I'm a reader who can read about a book a day if they're regular size, and so I'm used to being given multiple stories a week and thinking about everything in the books. And I'd never read two books at the same time as it'd be too confusing for me and the authors. But I was wondering would it bother you?
I'm wondering because the authors I am betaing for don't know as I've been reading the manuscripts and haven't emailed them about it yet; but I wanted to know as I haven't found anywhere saying that a beta can't have more than one author but I'm sure some authors might be a little uncomfortable with it or not even want their beta reader to be reading for other authors.

So how would you feel about your beta reader also reading for multiple other authors?

Wouldn't be a problem for me. After all, if you carry on beta reading, you'll have to work with more than one author, unless they can produce books as fast as you can read them.
As long as you give them a rough finishing time, and don't leave them hanging with baited breath, I doubt very much that it would be a problem.
It is polite to say I've got X books in front of yours, but I'll let you know as soon as I start, it should be in around X days/weeks.

No problem for me. But some authors are quite paranoid! ;) It's obvious that if you're a voracious reader you'll try to find as many books to read as you can.
The only thing is - complete what you start (and if you can't finish for whatever reason, tell the author). Don't vanish because you're overwhelmed with betas!
Happy reading and commenting!

I'm a writer, and as a regular reader I've read the work of many authors.

If ever an author ever offers to pay me enough to never read the work of another author that would be one thing, but since that has not and likely will never occur I'll continue reading whatever strikes my fancy.

Most writers will recognize that they aren't the only people with stories to tell to go along with a limited pool of alpha or beta-readers.
