Re: fictional authors/bookshevles. Reference the ideas or ideals you want the books to be about. If you describe the overarching concepts you are looking for, or the author as a legendary/authortative figure in his or her field, you can convey any subject or allude to anyone without actually naming names. Your more savvy readers will get who you are referencing, and the others will at least understand that the fictitous author/book is to be regarded as an authority on the referenced topic.
^This is what I was trying to say haha.
