Description
From a Google Books link, generates wiki markup in the
{{citation|...}} format, suitable for inclusion on Wikipedia:
http://en.wikipedia.org/wiki/Template:Citation
For example, when at the URL:
http://books.google.com/books?id=_tnwmvHmVwMC&pg=PA5&dq=%22The+trouble+is%22
you can click "Show citation" to get
{{citation | title=Asymptotic Methods in Analysis | author1=N. G. de Bruijn | edition=3, illustrated | year=1981 | publisher=Courier Dover Publications | isbn=9780486642215 | page=5 | url=http://books.google.com/books?id=_tnwmvHmVwMC&pg=PA5&dq=%22The+trouble+is%22}}
which is in the right format for Wikipedia, more or less.
Changelog:
Earlier history trimmed as this is a variation.
2009-09-28 A number of cosmetic and bug fixes.
- Now handles multiple line titles.
- Alert box changed to editable text area with optional format buttons.
- Trim button added to give a cut down version of the book page.
- Citation format breaks name into first and last names (not 100% accurate but good for 95%+ of situations).
- Auto-naming of ref tag based on author name and year.
2009-09-29 Fixed bug with hyphenated surnames and wrong matches for nobiliary particle
2009-09-30 Added sort to bring name, year, title at the lead of citation and improve Harvard cite,
skip firstname/lastname split for foreign characters.
2009-10-06 Bugfix on Publisher using "&", surnames using "'" and Harvard citation building
-17 Add inbuilt help button
-21 Add droplist of searches
-23 Make ref button fully toggling, expand button now toggles, url button toggles,
editors button toggles, fix box width, improve search droplist
2010-01-13 Change default to editors not showing.
2010-05-09 Allow c+cedilla e+acute e+grave in author name. Change contact details. Default to no url.
