I'm usually a buy it person, too, but our small apartment is already filled with books and DVDs (I actually have several books hidden underneath the couch) so I had to put the brakes on my purchasing. I'd buy ebooks, but I can't seem to stomach paying
more for ebooks than what paper books cost. Seriously, if I can buy a hardcover copy of a book for $18, I don't want to pay $25 for the ebook version.
Besides, I also read a lot of trashy romance novels for mindless entertainment. I won't ever read those again so the library's pretty good for that.
By the way, I just checked the NetLibrary site for LAPL, all it had was Project Gutenberg/public domain ebooks. I even tried searching for titles that I have checked out so I know the library has them and those didn't show up in NetLibrary. It seems the NetLibrary site for LAPL is only for direct reading of ebooks via web browser. I guess licensing restrictions would forbid them from making copyrighted ebooks available for everyone simultaneously via NetLibrary.
