The paper includes three parts. The first part offers a review of the debate on reference linking started in the 90ties, of the context, the discussions and the achievements of it, from the emerging of the "appropriate copy" problem, through the proposal of permanent identifiers, until the rising of the OpenURL solution, which appears rather close to the library tradition since proposes an indirect linking based on a standard description and aimed at the delivery of extended services to final users. The second part of the paper focuses on a case study, the home Brown OpenURL resolver at the University of Pisa: a linking tool under library control seemed a desirable addition to the Pisa library system, where no unique catalogue access to the different print and digital resources was available; it was self developed since linking tools appear to be more effective the more they deal with the local situation (i.e. the more they support customization), and in this case orientation toward the local situation has meant orientation toward the hybrid library, i.e. attention to opacs, traditional services, and not only to identifiers but also to bibliographic metadata. The application has been developed from the Perl script of Andy Powell known as UKOLN resolver, with relevant improvements: compliance to OpenURL 1.0, profile SAP1, interoperability with the local A-Z list of e-journals, inclusion of sources and targets actually subscribed to or used at the University of Pisa. It is not intended for generalization but for availability to the developer community under the GPL licence. The third part shortly traces a review of the newest applications of the OpenURL standard in the context of web 2.0. [ABSTRACT FROM AUTHOR] |
