Several libraries I visited had displays of staff reading (and I have see this is libraries in Australia too). There were different methods used, and they all looked good. This is impressive passive reader's advisory work.

Cambridge Public Library has descriptions of the kinds of reading and watching enjoyed by different staff with groups of selections, rather than individual ones.
An important thing to remember is to please use suggestions not recommendations, makes it easier to try, but also less judgemental if you don't like it (and you want to go and talk to staff seeing suggestions for reading you make like). It also does not imply you are a failure as a reading if you did not enjoy the suggestion, but it can feel a little harsher if you did not like something which was recommended. We all like different things, and sometimes it is the timing which is wrong and other times the title. It is not the reader who is wrong.
