Voracious book lover but find it difficult to get to the local library? Australian book rental site Slim Ink could solve your reading woes. Like previously mentioned US-only service BookSwim, Slim Ink takes the DVD rent-by-post concept popularised by NetFlix and applies it to books, sending out titles you select along with a post-paid envelope to swap when you're ready. Plans range from $14 a month for a single book to $60 a month for a dozen out at a time. While the range isn't gigantic (and there's no download option), this is a good solution for people who can't access existing libraries (because of location or work hours) and don't want to build a collection of their own. If you've tried it out, let us know your experiences in the comments. [Slim Ink]
