					Periodicals Archive Online Inbound Linking
This document describes the functionality supported by the Periodicals Archive Online link resolver module for inbound linking from
external resources.

Target resources
The Periodicals Archive Online link resolver provides support to enable third-parties to link into the product at both journal and article
level. The product performs a search based on the meta-data provided in OpenURL format. (This is sometimes known as “fuzzy inbound”
linking). The link resolver supports selected syntax from both versions 0.1 and 1.0 of the OpenURL standard.
