<p class="MsoNormal"><span style="mso-fareast-language:EN-US">Hi Akshat, the offset param defines how many items to skip before beginning to return rows. That means that to get the next page you have use offset=30 for your second request, in general you should
use something like<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">offset=0<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">first call: offset=1&limit=30<o:p></o:p></span></p>

<p class="MsoNormal">I'm trying to get all the years of occurrence for a specific organism.<o:p></o:p></p>
