In spite of not posting here for nearly a year, I have been doing a lot of work on the back end functionality of the book database. The biggest and most visible feature is a change to how quotes are being stored. Originally, all quotes were tied to specific "reads" of a book. Now, however, they are separated out into their own table, which gives me a lot more freedom to deploy them independently.
The upshot of all this is that I have deployed a new quotes page which lets you search for quotes by book, by quote type (I will be adding the first and last line to every book I read in addition to any favorite quotes), by author, or even by keyword. You can also choose to restrict the results to only show quotes that will fit into a tweet. I've also provided the means to permanently link to a quote so you can refer to it in the future and to download all the quotes in the database as a .csv file in the event that you want to do your own thing with them.
I will be continuing to go through and adding the first and last lines to all the books I've read (ever!) so keep an eye on the quotes page because it will continue to fill out over time. If you are interested in helping out in adding first/last line quotes please let me know. My ultimate goal is for this to become the most robust first/last line resource online and I know I'll need help to get it to that point. I'm also interested in any quote related suggestions you may have, so feel free to leave a comment or send me a tweet if you have any ideas.
