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 offset=0 first call: offset=1&limit=30 then: offset=(limit + previous offset)&limit=30 I hope this helps, Fede.

I tried pagination and with the limit and offset parameters. For example: http://api.gbif.org/v1/occurrence/search?offset=1&limit=30 But I noticed that each successive page has duplicate results. For example: for the scientific name: Aaptos aaptos, I tried limit= 30 and increased the offset parameter as- offset=0&limit=30 and offset=1&limit=30 The two queries have 29 common results. Is this supposed to happen or am I doing something wrong? Thanks, -- Akshat Pant Graduate Student | University of Maryland Master of Information Management
