Books, Readers and Beyond: #52 What to Read Pt. 1

I am back exploring the infinite where cyberspace and libraries coexist. For this exercise, I played around with Reader Advisories.
I am a huge fan of Novelist, an online database that helps find books by author, title, genre, etc. I used it frequently to find new stuff to read. For this exercise, comparing databases and what they retrieve, I used Steve Martin's Shopgirl as my test subject....
In Novelist Plus, the top three results were Shopgirl (tsk tsk), Undead and Unemployed and Wolves in Chic Clothing. On my current reading list is Undead and Unemployed, which is the book preceding Undead and Unemployed. However, I don't see a direct resemblance between Shopgirl and the latter.
My second test involves What Should I read Next? The results were odd because it retrieved graphic novels. I enjoy graphic novel but I don't see any correlation between Shopgirl and graphic novels unless it was made into a comic book, in which case I would be thrilled! It was not a complete failure as I have found a book within these results that caters to my taste: The Dictionary of Failed Relationships.
Finally, I tested Library Booklists and Bibliographies with the same novel. This site appears to be the more difficult of the three to navigate but I like how titles are divided by themes and the themes are divided into more themes! Searching Steve Martin's name brought me to a list of Humor lists but not all links worked. I tried Dark Comedy, Contemporary Humor and a third that were not accessible. The general Humorous fiction did work and a few titles suggested included Jennifer Crusie whose novel I have read and enjoyed.
All in all, these sites are very entertaining and more engaging for the users. I think using these sources for patrons to use will allow them to get a better variety and a higher exposure to lesser known authors.
