New LOCKSS Release: Version 1.48

On 19th April, the latest major version of LOCKSS was released.

This is an exciting release for us as several significant new developments will help LOCKSS to realise its long-term potential. Along with bug fixes and a few tweaks to the user interface, LOCKSS 1.48 introduces the ability to serve content based on OpenURL queries against the metadata extracted from preservable content. Given a request using an URL, a DOI, or OpenURL parameters, the content will be served from local holdings if it has been collected. If it is not available locally, or the publisher has made available a newer version, the user will be redirected to the online copy.

To support this process, fundamental metadata that was lacking in some records has been filled in with the help of the ISSN International Centre. A new tool allows title-level metadata listing the complete holdings available in LOCKSS to be exported in the industry-standard KBART format. The next version will provide the option to export only the holdings preserved in a particular machine. The export is available either in CSV format for import into a spreadsheet or library systems, or in a customisable HTML format which is useful for online browsing and searching. Link resolver vendors such as Serials Solutions (360 Link) and Ex Libris (SFX) are working with us to include the exported LOCKSS holdings data in their Knowledge Bases and to develop the components required to support OpenURL resolution to LOCKSS.

Additionally, a new metadata extraction framework supports the building of a database of article-level bibliographic information from preserved content.
