If the items of a book are on hold already, checked out, in transit, etc., it would be helpful to see that again on the place hold form. (Perhaps in a yellow dialog box on top.) The information is on the search results now or in the items table on the form but only after clicking the menu and clicking 'specific item'. If the user does not open those and just adds a biblio level hold, it would be helpful to have them informed already about the availability status. Note that a user could reach the biblio detail page also from another page than the search results. Perhaps via a list or a search with only one result?
