[OAI-implementers] How many records should typically be returned over OAI-PMH?

[Dan Stowell]

Thanks - but yes, I'm aware of the resumptionToken - I just wanted to know 
whether there's a de facto standard for how many records to return in a 
single response, before giving the resumptionToken.

Best,
Dan
