The List: As new movies come out, I add them to a list and about 6-12 months after the film comes out, I can usually find it in the library's database. The more popular films and blockbusters frequently have a long waiting list, and there is a limited number of films that you can add to your hold request queue, so it's important to develop a system for choosing which films to request; otherwise, you end up filling up your queue with DVDs that won't be available for check-out for several months or more. It's good to mix in some older films on your list that you have wanted to see for a long time; this helps fill out your queue when you're waiting for newer films to become available.
The Check-Out and Return Cycle: Once you have placed requests for DVDs, you then have to keep track of requests as they become available and are held for you at your branch. Holds are placed for a limited amount of time which varies with different library systems, so you need to pick up the movies before the hold is lifted. Each film will also have its own rental period; some can be checked out for longer periods than others, and some items will be available for renewal while others will not. Once you check out the films, you will want to watch the ones that need to be returned first (I separate my DVDs into two separate stacks to manage this). Those that have the possibility to be renewed, if you have not yet watched them by the end of the rental period, you can renew online to buy some more time. Try to refrain from renewing at the start of the check-out period because it won't add any time onto your existing deadline.
And that's it! Once you get a hang of it and understand the ins and outs of your library's system, you'll wonder why you didn't try this sooner. And if you find yourself having to let go of your cable tv service, you may find that between online viewing and your library rentals, you don't even miss TV--I know I don't! Happy viewing!
