There is a site called Goodreads. I'm a member and one of the things I enjoy are listing the books I'd like to read. I have gone from "Gosh, what to read now?" to "I will never have time to read all of this!". It is a great reminder of things I see as I go.
Goodreads is also accessible easily by my phone (they have a mobile site), so I can see my list of books when I'm in the library or bookstore or whatever. I can also see what 'friends' are reading - although currently I really only have one friend who is active on it.
You can also put what you are currently reading. I do this mostly b/c my friend who is active on the site loves to see this stuff. Since she is interested, I take a minute and throw it up there. It isn't time consuming.
The site send out a month newsletter that I don't pay too much attention too. Sometimes they have interesting articles on or about authors I've recently read or their books (or both). So I do skim. Today, at the very top of the email was this:
Oh my...really? It has been THAT long? The sad thing is...I am really still reading this. I had to put it down for awhile because my eyes had been really bothering me during my first trimester. Then I sort of forgot about how much I enjoy reading...and recently picked it up again. Like...last week recent.
But that is so sad that I've been in this book for 157 days...it really is a pretty good book.
