Ideen und Entwickler gesucht: Open Book Widget

John Miedema freut sich über 1000 Downloads seines Open Book Widgets. Gleichzeitig läd er zur Mitarbeit ein:

What is most compelling is that OpenBook is free and open source — the entire codebase is available for inspection and innovation by the library world. To facilitate that sharing, I invite you to join a conversation that is starting about open source book widgets. No techie experience required, only an interest in book widgets, those little interfaces for sharing book data. Join our discussion list. Edit our wiki. Or just have a peek. More information to follow later.

Dem Aufruf möchte ich mich anschließen. Entstehen kann im Idealfall eine Programmbibliothek, die Zugriff, Verbreitung und Verarbeitung bibliographischer Daten im Web einfacher und gebräuchlicher macht. Das Projekt befindet sich noch ganz am Anfang. Einflußnahme auf die Ziele und die Struktur sind also noch möglich und sogar erwünscht.

OpenBook WordPress Plugin: Open Source Access to Bibliographic Data

John Miedema schreibt in der neuen Code4Lib-Ausgabe über sein OpenBook WordPress Plugin

OpenBook is a WordPress PHP plugin that implements the Open Library APIs to insert book covers, titles, authors and publishers into web pages. The motive behind the development was to provide an easy alterative to the common practice of linking to Amazon. Open Library was selected as a data source because it is both open source and open data.The plugin is useful for book reviewers, library webmasters, anyone who wants to put book covers and data on their WordPress blog or website. The plugin also allows users to add links to publisher websites, a feature that was considered significant to independent publishers.

Damit wäre die Arbeit an ISBN2WP wohl weitgehend überflüssig und wird folglich eingestellt.

ISBN2WP – Alpha Release


Read the first thoughts about a plugin that sucks bibliographic data from library catalogues here and here (both German). Since it does a bit more than just connecting to a SRU service, I renamed it from ISBN2SRU to ISBN2WP. Another name change is very likely to come soon.

How it works

Just insert an ISBN into your posting:
The plugin grabs bibliographic data (Dublin Core) the Common Union Catalogue via SRU, adds a search link to GVK via SeeAlso (I currently use isbn2gso) and includes a OpenUrl COinS. The latter makes it easy to grab the bibliographic data with, for example by Zotero.

A short showcase…

First plugin, first screencast…

Update: The youtube clip is of rather poor quality. You can view the pure flash file here

To do

  • The COinS export is anything but perfect, and so is the presentation of the given Dublin Core metadata. Any ideas how to improve this, anyone?
  • I didn’t manage to include the wordpress options hook properly. Help!
  • Links to diverse services will be integrated (Scirus, Google Scholar …)
  • A bunch of other things. For example support for DOI, URN

Download & Installation

  1. Extract isbn2wp (ZIP) and drop the folder “isbn2wp” into the plugins folder (/wp-contents/plugins/) of your WordPress installation.
  2. Go to your WordPress settings page and activate ISBN2WP.
  3. Start testing
  4. Leave a comment if you discover bugs or if you want to improve ISBN2WP.


Thanks to Stefan, Meinhard, Lambert, Martin, Jakob, Patrick, Edlef and all the others who helped me with hints and cheats to build this draft of a useful plugin! This plugin appears by courtesy of the library of the University of Applied Sciences and Arts Hannover.
