Charges for Services

There are no costs for posting papers for groups who designate someone to fill out the submission forms and upload papers.

There is a small charge per paper for groups that have each author submit their own papers, or have staff at the University of Minnesota assist with the process. Charges are from 1 US to 5 USD per paper depending on how much extra processing is involved, for example adding conference cover pages, or splitting journal issues into individual articles prior to uploading.


AgEcon Search does not hold the copyright to articles, working papers, conference papers, or other materials available in the repository. Authors of papers posted on AgEcon Search retain their copyrights. When authors have assigned or transferred rights to them, journal publishers hold copyrights to articles published in their journals which are contained in the AgEcon Search database. Materials will be removed if it is found that copyright has been violated.

Some authors request that their papers not be cited. This condition is stated clearly on the cover page, and we ask that users respect these authors’ wishes.

AgEcon Search requires no license agreement with or permission grant to others who want to link to content in the AgEcon Search database.

AgEcon Search, its staff, and the University of Minnesota are not liable for any loss, damage, or costs arising from any infringement of these rights.
