Bad line break on title page

[Allen Downey]

Let's split the subtitle like this:

Computer science and
Information Retrieval in Java

[Kristen Brown]

in post-intake PDF, this fits on one line. OK?

Also, the wording in the PDF is slightly different. Which version of the subtitle should we use?

[Allen Downey]

"Algorithms and Information Retrieval in Java" is correct, and if it fits on one line, even better.
