While not intending to disparage example sentences, which can be quite useful, I suggest that they sometimes serve as a crutch. That is, the very fact that they are so useful often reveals inadequate analysis and presentation of information. Of course, that is to be expected in earlier stages of work, but at some point one wants to figure out exactly what a word means and define it properly, to work out its syntax, etc. A plethora of example sentences often serve to allow the diligent reader to work these things out, to varying degrees of adequacy and accuracy, when the author of the dictionary has not done so. In many cases, the number of example sentences can and should be reduced in favour of better definitions and grammatical information.<br>
<br>Of course, one wants to have access to the data on which the information in the dictionary is based, but it does not necessarily all belong in the dictionary, especially if the dictionary is on paper and/or aimed at less advanced users.<br>
