I just created my shelfari bookcase. It's a mix of stuff I've really enjoyed recently and over the last say ten years or so. So lots of stuff! And I will keep adding to it as I shelve books at the library and see a book and remember "oh yes that one." Every single one of these books grabbed me and allowed me to become absorbed in their worlds, they are all books that when I finished the last word I sat back and muttered "wow."
Three of my favorite bookshops in San Francisco- City Lights in North Beach, Booksmith in Haight Ashbury and Dog Eared Books in the Mission- all have sections with an eclectic mix of stuff selected as recommendations by staff. So my shelfari bookcase is inspired by those great bookshops.
