For most of the articles we have used the author's summary or we have created a brief description that emphasizes the practical value of the article. In some cases we could not locate a copy of the article to annotate. Copyright laws prevent us from providing copies of the articles. In most cases there is no charge for this service. You may find duplicates of some articles.
Some articles contain numbers just before an author's name.
This notation is left over from the hard-copy cataloguing system and the numbers should be disregarded. Since new listings are continually added and updated, it may be that what or who you are looking has not yet been added to the Bibliography.
