A catagory for a database entry is a key notion for us. Basically it tells you what sort of an entry you are looking at. It tells you whether author of the book under review just made a serious error, forgot to mention something important, or the person who submitted the entry to the database thinks that there is something wring with the info author provided. Below is the list of catagories which you can currently find on the Database pages:

• Factual Error - a serious error in the book, author stated something that contradicts the verified fact. The Fact part of the entry will contain the correction.
• Incorrect Date - is used for an error that concerns various dates, usually for Pink Floyd shows. This is done to separate such errors from other factual errors. The Fact part of the entry will contain the date correction.
• Oops - is used to indicate simple to silly errors. Something commonly known, but nevertheless misstated in the book. The Fact part of the entry will contain the correct info.
• Incomplete Info - author provided only part of information, and it seems that completing it can benefit the reader. In some cases it is not clear whether the book did not provide complete info because the author was not aware of it, because he deliberately chose not to include it, or because of the simple omission author made. The Fact part of the entry will contain additional info, and Analysis/Comments part may contain some speculations on the matter.
• Uclear Statement - two or more interpretations of what is written in the book exist, while not all of them have the same truth value. The Book part will state what exactly is unclear in the book, the Fact part will contain the factual info on the matter.
• Update - similar to Incomplete Info. The only difference is that the new info, has appeared since the book was published and is presented in the Fact part of the entry for the benefit of the readers.
• Internal Contradiction - when two parts of the book contradict each other, this catagory is used. In some cases the this is the only info one can extract as there might be no way of determining which one of the contradictory statements is true (or which statements are false). If this can be determined, the Fact part of the entry will contain this info. Otherwise, Analysis/Comments part might contain various thoughts and hypotheses.
• External Contradiction - there is an established contradiction between the information in current entry and information supplied by a different source/book, however, at this time it is impossible to determine which info is true.
• non-Floyd - is added to the entry catagory, whenever the nature of the facts considered in the entry is not directly related to Pink Floyd

In the future (a rather distant future), the Entry Category might become a base of a Project Errorfest Search Engine, should I decide to add some CGI. So far the Category is used strictly for informational purposes....
