Chances are, if you have lived in your house for awhile, your bookshelf is overflowing. Or you need to go out and buy one.
Luckily, we have moved twice in the last three years and I have purged, stored and handed down many books. For staging purposes in our house, we had to get rid of seven bookshelves that were around the house. We are down to three and one is mine, with about 1/4 of the books I own. As I moved, I was forced to really think about the books I wanted to keep. I noticed I had books that were never read on my shelf and when I read the blurb, I wondered why I even had it...so I donated those. All the preschool and early elementary school ones I used in teaching went into storage and hopefully will come back out when I get back to teaching this fall.
From an early age, I organized my books alphabetically by author. Here is a photo of my one bookshelf in my office...until we move at the end of June. Then, I can put up my other four bookshelves and fill them back up again. What do you have on your shelf? (I wish we could put a photo in the comments section so I could see...feel free to add a link if you have a picture of your shelf/shelves).
For the stories I write, I always have a character who likes to read. I may mention certain classics in the story but rarely do I mention books by name. Maybe, one day, when I become famous (ha!) and my character is reading a book in a scene and a reader asks what was she reading I will tell them what was in my head at that moment :-)
