As I suspected, it was user error. &nbsp;I wasn't encoding the resumptionToken
correctly. Now it works for me. Thanks! <br>

  <pre wrap="">resumptionToken is no a verb, it is an exclusive argument for 
ListIdentifiers or ListRecords. Your request should look something 
like:

GET baseURL?verb=ListRecords&amp;resumptionToken=APPROPRIATELY_ENCODED_RT_HERE

where APPROPRIATELY_ENCODED_RT_HERE is the URL-encoded resumptionToken.

As far as I can see, this site works fine:

    <pre wrap=""> Hi,

I've been trying out the OAI 2.0 protocol on the NSDL repository at <a class="moz-txt-link-freetext" href="http://services.nsdl.org:8080/nsdloai/OAI">http://services.nsdl.org:8080/nsdloai/OAI</a>  When I send the following request <a class="moz-txt-link-rfc2396E" href="http://services.nsdl.org:8080/nsdloai/OAI?verb=ListRecords&from=2002-01-01&metadataPrefix=oai_dc">"http://services.nsdl.org:8080/nsdloai/OAI?verb=ListRecords&amp;from=2002-01-01&amp;metadataPrefix=oai_dc"</a> 
I get back an imcomplete list of 250 records and the following resumption token 
"from=2002-01-01&amp;amp;metadataPrefix=oai_dc&amp;amp;origRequestTime=2002-12-16T19:43:00Z&amp;amp;

    <pre wrap="">When I try to use the resumptionToken verb and give it this token 
(whether encoded or not), I get "resumptionToken is not a legal OAI-PMH 
2.0 verb." which seems untrue based upon the OAI protocol document I'm 
reading.  I can't tell whether that is really an illegal verb or the 
NSDL implementation is wrong or I'm not using the resumptionToken verb 
properly.

Any help would be greatly appreciated.
