Bibliography: Content that looks like HTML markup is corrupted

[MattHeffron]

Describe the bug
Content that looks like HTML markup (but isn't) is corrupted in some contexts.

To Reproduce
Steps to reproduce the behavior:

1. View the bibliography on the website
2. Locate the bibliography entry with title starting with: "Special Files on"
3. Notice that the full title reads: "Special Files on <Test>ARs>"
4. In the Abstract, the same directory path is corrupted as: "...special files in the ARs> directory..."

However:
5. Locate the bibliography entry with title: "Debugger, Error System, and Unwinder test report"
6. In the Abstract here the similar directory/file path: "<Lyric>Basics>Full.Sysout" is displayed correctly on the list of entries page, but it is corrupted on the corresponding single entry page: "Basics>Full.Sysout"

Expected behavior
Content that looks like HTML markup (but isn't) is displayed correctly, in all contexts.
