I have just been reading Crystal Paine’s Biblical Womanhood blog. She was teaching on frugal living. If you have to, want to, or believe you should live frugally, spending less than you do, she can probably tell you several ways how.
One of her points was that she gets books from the library, even through interlibrary loans, instead of buying them. She even does this for her young daughters. (I know for a fact that she owns a few books, considered school books, that teach sign language or catechism.) From a woman who writes and sells books, I find this an ironic confession.
For myself, I’m a writer. Someday I intend to publish something and get paid for it. In the mean time I blog, for free, and spend all my writing energy doing this much easier exercise instead of putting together a book. Yet I sympathize with authors, feel for the mass of books out there as competition. On top of all this we add libraries.
So here is my solution, killing two birds with one stone. I use the libraries. In this way I discover whether a book is worth purchase. (If it wasn’t worth purchase to anyone, it ought not have been written. But some people purchase unworthy books – like all the romance novels we see at garage sales and used bookstores.) After reading a book that I like, I will usually add it to my list to buy. There are a few instances in which I will buy a book without reading it: I trust the author, I trust a reviewer, I trust the store, or I get a really good deal. Which brings up the fault in my reasoning. I would much prefer to own secondhand books than to pay full price in most cases, especially if the author is already mainstream. Some books I see as supporting a ministry when I purchase them full price as directly as possible from the authors.
All this to say I am almost never completely frugal with books. I would not want to have the library own all of my favorites for me. Though I am willing to live in an inexpensive apartment my whole life, and to not eat at fancy restaurants, and not buy new clothes (or many clothes). Though I can resist going to the movies, or buying frivolous things; I have every intention of owning shelves and shelves of books. To this end I never refuse to spend money on a good book. And I have stacks of books in my room.
Just recently I cleaned and rearranged my room in order to shelve all of the recent purchases that had been stacked on my floor. Immediately following this burst of energy and organization, I went out and bought stacks more books. Stacks. And then I went to the library, where I checked out seven large books as research for my writing. (One of them is about Iceland in the Middle Ages, and has me all bound up in that world; look for the review!) So my floor is just as covered as ever with books for my library.
If I ever move or get very organized (and ambitious: buy new shelves, rearrange my whole room…), I will take massive pictures for you. In the mean time this is what you get.

I totally agree with you about using libraries to determine if a book is worth the purchase. Most major bookstores allow customers to read at their leisure for that same reason. Apparently, enough people end up buying the book they get hooked on to keep them in business.
Off topic but related…..I have also heard music that was downloaded for free and actually had to search out many stores to actually find one CD left of a particular unknown artist or two that I would have never heard had it not been for free music and trying it out first, not that I’m in favor of copyright infringement (if that’s what downloading it for personal use really is). 😉
I will never give up on real books, so if/when you publish, I’ll find what you’ve got and support you with a first time purchase…and a second if you’re good! 😉
