Book Requests error if label is the same

[h3mmy]

Some book requests will error out if there are duplicate titles as options.

Should be a pretty straightforward fix. But there may be instances where a discriminator is important. Example different publishers can have different versions. Some versions might be censored for particular regions, etc.

The current selection from search is lacking and could be improved.
