Many titles provide transcripts (look at the tabs in the box to the right) which can be helpful when citing. Some also allow searching within a transcript to more easily find relevant information, however you need to scroll through the transcript to look for highlighted terms. It does not automatically jump to them.
Because your topic spans several collections, we recommend that you do a general search for a word or phrase rather than choosing a single collection. Broadening your search term and then searching within the resulting titles takes time but usually generates more results.
