// These are the sites currently supported by CiteULike for automatic parsing
// of bibliographic information. If non of these URLs are found,
// the primary link is returned, and the user has to manually enter the information
// into CiteULike.
//
// The order here is deliberate:
// First, governmental, academic, and non-profit citation sites,
// then, the specific sites and journals supported by CiteULike,
// and last, the commercial citation collections.
//
// Entrez PubMed was put first, deliberately, because if its vast cross indexing
// of papers in the life science, with links to keywords, gene sequences, etc.
// which are not found on the publisher's own sites.
//
// Currently this script ignores search results that are books.
// When WorldCat support is included by writing a plugin in CiteULike, I will
// then add the links for book results too.
//
// OCLC WordCat is included here instead of Amazon.com because this provides
// bibliographic data for most books, as well as which libraries have them
// in their collections. Another script or extension that can parse the ISBN
// on a page can turn that on the WorldCat page for the book into a link to
// Amazon.com, if desired. There are scripts and extension that do just this.
// If anyone has a suggestion as to changing the priority of these, please
// post it to the CiteULike Discussion Group (citeulike-discuss@lists.citeulike.org)
// or email me directly at ted underscore kandell at yahoo dot com.
