Use the Search at the top right of the table. Some example searches: klein, klein patent, commercial tweeter, corona wind paper, 1951 etc.  Use surnames, the search updates as you type so partial words are all that's needed. Add the word key to your search to reduce the number of articles to some of the more useful.

Click the Columns button to switch off columns. Click column headings to sort the table by that column - so click on Year and it will be chronological, click again to reverse.
