I have something over 200 books in one small space...they always surround me but I like it that way. I've always dreamed of having a proper library or of living in a library, getting locked in a library, etc., etc. Anyway, these hundreds of books were more numerous in the past and I had to (painfully) pack some away because of allergies, etc. Books do unfortunately hold a great deal of dust and other allergens (incl. mold if there is enough humidity in the air) because they are made from organic material. Luckily, we live in a digital age and many of those books that I might have bought in a used bookstore, along with all the requisite nostalgia causing mustiness, I now own in electronic form. With a large enough screen and good backlighting, I have found reading text in electronic form to be quite rewarding. Recently, Sony came out with a nice reader just for this purpose. This may be a little reminiscent of those flat pads the crew used to read from on Star Trek: TNG but, even without being a fan of new technology, anything that allows me to carry around an entire library of books in my pocket is a winner with me. Note: I carry about 180 titles on my PDA and have had no difficulty reading from it, even in dimly lit environments.
