The ASU Herbarium is part of the SEINet consortium of collection databases. Virtual access to millions of herbarium records can be found here.

Information regarding the various capabilities of SEINet and the Symbiota software such as mapping, making checklists, and using interactive keys, can be found at the following links:  making_good_use_of_seinet-liz_edits-may_2016.pdf.

For more functionality of the SEINet portals and a review of the Symbiota software platform see Gries et al. 2014. Symbiota – A virtual platform for creating voucher-based biodiversity information communities.

SALIX is a software system designed here at ASU to capture herbarium specimen label data with the use of optical character recognition technologies and transfer those data into a database. The following link will take you to the most recent version at the idigbio portal.
