Most databases won't have many articles on specific neighborhoods, as that level of geography is very limited. But, you may well find related articles for San Diego, California, or the United States that can provide context for your neighborhood profile.
In many databases, you will see a "PDF full text" or "HTML full text" link next to a citation. If so, clicking on the link will bring up the full text of the article.
If you don't see one of those links, you should see a
