Today I spent some time studying my bookshelves. I have many new additions that need homes on the shelves and off from my dining room table, so I had to look to see where they could go. The answer, I need a new shelf. And I just got one in August. Of problems to have, I embrace this one.
My shelves are
highly organized. I am developing quite the library and in order to find things, well, I find it quite imperative to have genres/styles/time periods/authors (size of book also factored into arrangement) in mind when looking for a particular book. The system is flawed as I had thought I'd lost a book only to find on an unexpected shelf. I realize by looking at the size of the book and that it was a hardcover it explained the placement, but still, flawed. And then there are the books that I realized I had forgotten all about. But that is another topic.
As I was looking through my stacks I came to the conclusion that with the exception of 1 bookcase, I have determined my own "personal" Canon that appears in bits in pieces on my shelves. Whether it be in current fiction (my book shelf or hardcovers and book shelf of paperback) or my theory bookcase (yes, I have enough books on Aesthetics, Literary Theory, Cultural Theory that they have a bookcase unto themselves, a rather large one). But this really shows up where literature scholars would view I have
The Canon shelved (1 of 2 such cases, but this one is purely focused on this type of literature). But I have made it my own, kind of, influenced of course by the actual Canon without doubt. My Canon is influenced by the type of literature I am drawn too, texts that challenge me and make me think, I am not a big reader of "pulp fiction" these books just do not motivate me to read (what they do is for another time). I will say it is not perfect space creates the imperfection, but does not detract from my point.
On the top shelf (oh, I built this bookcase at 12) we have the top of my Canon:

For me Henry James is my main man. And he has the place of honor on this shelf. Tucked next to him his contemporary and competition Edith Wharton, then there is James Joyce. These are not literary lightweights. And both James and Joyce rarely taught. The Canon thinks that they are too difficult and rarely make it to students. Shameful (they are not too difficult to teach, this must be overcome), but they make my top tier Canon placement.
The Middle Shelf, still weighty but not Henry:

Being a Modernist girl at heart, this would be my literary time period (Henry James and Herman Melville are both early Modernists, but this is another topic), no surprise to find Fitzgerald, Ellison, Waugh, and Chandler located there. All powerful and important authors, but in my opinion not up with James. Hence their placement on the second shelf.
Lastly the bottom shelf, the dregs (not really), the might as well be pulp (just kidding) it's barely literature literature (again I kid) aka they're no Fitzgerald:

Smattering of authors, Kundera, Camus, random Modernists texts, and others round out this shelf. All great texts by great authors (except for the Hemingway), but not Henry James of F. Scott Fitzgerald to me. In my canon, it seems I have ranked them third tier, at least in this little microcosm. If the shelves were larger and fit more, these would be the books buried at the bottom of the others, because the likely hood of my wanting to pull off at random times is low.
Do we all in some way create a Canon of our own? I say yes. I doubt though that everyone displays it in the same manner which I unconsciously did, or do you?
