Unfortunately, I didn't know what either a Fouml;hnwelle or a blow wave is, so I declined. He then told me he had found this sentence in a German phrasebook he recently bought.I was interested and had a look at some German phrasebooks. I think they are great tools to get around in a foreign country, although I personally think that some of the phrases offered just don't make sense. For instance, in one phrasebook, I found a series of pickup lines, including the ingenious "You have a beautiful personality," something that didn't work for me either in English, in German, or in any other language! Some coital guidance could also result in other problems--you either have to remember all the things to say while you are at it, or you have to hold the phrasebook in your free hand. And, finally, "Blow waves are as dead as a pet rock," just to use another phrase.Anyway, we were discussing phrasebooks a bit, and Damon said that he wanted to do a book series on phrasebooks. He also mentioned that he would like to team up with his and my favorite acquisitions editor, Shelley Johnston, so I was in.While working on a concept, we found some differences between a language phrasebook and an IT phrasebook. For instance, a language phrasebook just contrasts the same sentence in two languages. However, this is not always helpful. What if you want to change the phrase a bit, for instance if you want an en vogue blow wave (an oxymoron, one might say)?So, we tried to create a concept that contains a lot of phrases, but all of them with good explanations so that it is easy to change the code and adapt it to one's needs. This, of course, makes the "foreign language" portions of a phrase a bit longer than the phrase itself, but we think that really helps when working with the book.I also remember one famous Monty Python sketch in whi
