Rearranging my library

I have a massive library.

My house has 2 bedrooms, and while I could have used the other bedroom for a guest room, I’ve always wanted my own personal library.

The only issue is, since I get books donated to me all of the time, they are always disorganized. I really wanted to sort my books alphabetically, and by series, but I’ve never had enough time to do so. I finally have a free weekend, and I have decided I am going to get all of the books sorted then. It would work out perfectly, because I actually had a HVAC appointment over the weekend as well. My HVAC unit is right next to my library, so the HVAC technician could work on getting my cooling device working again while I work on sorting all of my books. When Saturday came, I got started on all of my books, and I had been doing so when the HVAC professional arrived. I let him in and showed him where my air conditioning machine was. He started repairing it while I went back to my books. After working for almost 2 hours, I was really beginning to get hot, and even though I had ⅓ of the library sorted, I still had a while to go, and getting really hot was making it incredibly difficult to continue. I was beginning to consider quitting and redoing my books some other time, when the HVAC specialist got my air conditioner working. Suddenly my house was filled with a cooling breeze, and that was enough motivation for me to continue. I was able to finish putting away all of my books, and my library was finally finished.
