L is for look

"...look here," She opened one of the drawers and pulled out a small brown envelope. "This is the tune George Washington whistled when he crossed the Delaware on that icy night in 1777."

Hint: it's not historical fiction, but it IS fiction.

K is for kept

...kept here," said the Soundkeeper, skipping down one of the corridors with Milo in hand. "For instance, 

Here's a hint to the book I'm using: it's a children's book from the last century.

J is for jingles

...jingles and chimes and started down the hallway. 

"Don't you just love jingles and chimes? I do," she answered quickly. "Besides, they're very convenient, for I'm always getting lost in this big fortress, and all I have to do is listen for them and then I know exactly where I am." 

They entered a tiny cagelike elevator and traveled down for fully three quarters of a minute, stopping finally in an immense vault, whose long lines of file drawers and storage bins stretched in all directions from where here began to where there ended, and from floor to ceiling. 

"Every sound that's ever been made in history is...

I is for I

"...I seem to have a touch of static," she complained. "But what brings you here? Of course--you've come to tour the vaults. Well, they're usually open to the public only on Mondays from two to four, but since you've traveled so far, we'll have to make an exception. Follow me, please." 

She quickly bounced to her feet with a chorus of...

H is for how

...how I am."
"How are you?" he asked politely.
"Not very well, I'm afraid....

G is for great

Here we are at week two. If you know the book I'm using, just say something like this in the comments: I know the boo-ook, I know the boo-ook! But don't say which book it is, YET!

...great deal," though Milo.
"At one time I was able to listen to any sound made any place at any time," the Soundkeeper remarked, pointing towards toe radio wall, "but now I merely--"
"Pardon me," interrupted Milo as the phone continued to ring, "but aren't you going to answer it?"
"Oh no, not in the middle of the program," she replied, and turned the silence up a little louder.
"But it may be important," insisted Milo.
"Not at all," she assured him; "it's only me. It gets so lonely around here, with no sounds to distribute or collect, that I call myself seven or eight times a day just to see...

F is for FOR

"For someone who loves silence, she certainly talks a...

E is for enough

...enough, no one pays any attention to them these days.
"Have you ever heard the wonderful silence just before the dawn?" she inquired. "Or the quiet and calm just as a storm ends? Or perhaps you know the silence when you haven't the answer to a question you've been asked, or the hush of a country road at night, or the expectant pause in ta roomful of people when someone is just about to speak, or, most beautiful of all, the moment after the door closes and you're all alone in the whole house? Each one is different, you know, and all very beautiful, if you listen carefully." 

As she spoke, the thousands of little bells and chimes which covered her from head to toe tinkled softly and, as if in reply, the telephone began to ring, too.
