On the list of search results the Issue Date "1951-01-17-BC-OCR-Page-0012" is the link to an issue containing your search terms as YYYY-MM-DD and page order. Click on any link to view the actual page. Once you select an issue, you will quickly see the image of  just the single page where your search term appears.  If you want more context, view the entire issue from the issue listing page. 
The text you see in the search results may be inaccurate or garbled as Optical Character Recognition on old documents is not perfect, so try different keywords if you don't get the desired results. The text will be clearer in the full page view of the selected reference. The file linked to each search result is a fast-loading single page PDF and will be an image of the original where the search reference occurs. You will see a clear page just as published when you select any of the results. There are now 310,000 indexed pages so enjoy your exploring of radio's history!
You may view entire issues by selecting this magazine's page at the home page of this site.
