I'm sure you already saw this URL, Alice, but maybe this is a more appropriate place to post it:

It's some guy in Toronto who has a huge number of songbooks for sale, and I couldn't believe the variety available. Trouble is, they ain't cheap. Guess I'll have to restrict my search to thrift shops and used book stores. A person could go broke.

As for typing songs already posted, we have that nice search box in the upper right corner of the screen on many pages. If you put up too many reminders, they just get lost in the clutter. If people request lyrics that are already listed in the database, the rest of us can just post a gentle pointer - but I think it's important to preserve the friendly tone of this group by always remembering to be gentle. Harshness gets amplified in a forum like this, and it can really hurt feelings.
I think it might be better not even to bother posting reminders to those who post lyrics already in the database - unless it gets out of hand. As I said somewhere else, sometimes it might be good (within reason) to post lyrics within a thread that's discussing a song, rather than pointing to the location of the lyrics in the database. Otherwise, we don't all know what we're talking about.
