Download metadata merge result ?

[abuck]

Trying to get metadata from one book and I noticed that the result is getting merge.

There are actually two books that is getting returned in the log:
1- CSS and Documents
2- Cascading Style Sheets Specification, Level 2: W3C Recommendation 12-May-1998 : Rec-Css2-19980512 (Open Documents Standards Library)

But only the second one (Cascading Style Sheets Specification, Level 2: W3C Recommendation 12-May-1998 : Rec-Css2-19980512 (Open Documents Standards Library)) is showing in the GUI. Since my book is CSS and Documents, I cannot pick it. If I go to view log, I can see that my search got merged for some reason...

Two questions:
1) What are my options if I want to choose the first book returned without getting a merge ?

2) Why I am getting a merge here exactly ?

thanks !

Cascading Style Sheets (CSS) is a powerful tool that transforms the presentation of a document or a collection of documents, and it’s spread to nearly every corner of the Web—as well as many non-web environments. In this free introduction to Cascade Style Sheets, you’ll learn how CSS makes it possible for you to completely change the way document elements are presented by a user agent. You’ll discover the origins of this specification and how CSS styles work with HTML.
Learn how you can choose style sheets based on the features of a given media type, including desktop screens, web-enabled phones, digital projectors, TVs, Braille devices, print documents, and even various audio renderings of a document. CSS and Documents is an excerpt from the forthcoming 4th edition of CSS: The Definitive Guide.

Complete and up-to-date specifications of Cascading Style Sheets, Level 2 (CSS2).
Ideal for program designers, HTML Web page authors, and others who need to keep abreast of current publishing standards for the World Wide Web.
Describes how to attach a style sheet to an HTML document so that its appearance (fonts, colors, spacing) can be accurately defined.
Explains "cascading" nature of style sheets-enables users to set display preferences.
Style sheets describe how documents are presented on screens, in print, or even how they are pronounced when spoken using a computerized speech synthesizer. The specifications for Cascading Style Sheets Specification, Level 2, have been prepared by the World Wide Web Consortium (W3C), an independent and international standards body devoted to furthering the technologies used on the World Wide Web. The W3C has produced two recommendations (CSS1 and CSS2) which are widely, although not consistently, implemented in browsers, such as Microsoft Internet Explorer and Netscape Navigator. The CSS2 specifications are an enhancement of the earlier CSS1 specifications, and provide greater control and flexibility in rendering a page on screen or paper.
By attaching style sheets to documents on the Web authors and readers can influence the presentation of documents without sacrificing device-independence or adding new HTML tags. This book contains the complete and most up-to-date version currently available of the CSS2 specification. It's designed to be a handy desktop companion, saving you the time and expense of printing the documentation yourself. It is also useful when viewing the online version of the CSS2 specifications is inconvenient.

The merge is, as I understand it, between the identical matches used from Amazon and from Google. Since there was no match from Google, I don't think there was a merge of metadata.

Amazon returned two matches, one was right, the other was wrong. I suspect that calibre use a very simplistic method to choose which to use. Either the last one or perhaps the one that is longest. Or has the earliest publishing date. Either way calibre can easily be fooled if more than one matching book is returned.

To make Amazon return only one book you could include the name of the author in the search. I suspect that only one match will be returned from Amazon then. And perhaps there will be a match from Google as well.

So the problem was that you provided too little information about the book to make the search successful. And Amazon tried to be helpful and suggested a book (document) that was about the same topic.

If you had run the search interactively you could have compared the matches and chosen the right one.
