ISBNScraper search-results change over time

[Til Barthel]

The ISBNScraper searches on www.worldcat.org for a specific ISBN and extracts the first result. Over time, the search results will change. For example, if a new edition of the book is released or an entry for a chapter of the book is added, In the worst case, the bibtex of the chapter will be returned instead of the book.

It is possible to be more specific in the search. For example, one can add the publication period, the format of the entry, or the language. The AmazonScraper can, for example, extract more information from amazon.com and add it to the search query.
