Need to re-enable an onmouseout that was disabled in onclick event

I have searched here and on the Internet for code that can re-enable an onMouseOut that has been disabled in the onClick code. I have found things but nothing that works in my situation.

On the page there is a container div that holds two divs, one for an image and one for its corresponding text. Under the image are four links (1, 2, 3, 4) laid out in an unordered list. When the visitor rolls over the #2, the image needs to change to img2, the matching text div needs to go from "hidden" to "show". The onMouseOut resets the image and text to the original versions. The onClick changes the image/text to whatever # was clicked and then disables the onMouseOut.

Now I need a way to make the onMOuseOut work again the next time the visitor rolls over that #link. As I have it now, once the onMouseOut is disabled, it stays disabled until I reload the page.

Here is the code so far:

<head>
<script>
if (document.images) {
book1 = new Image
    book2 = new Image
    book3 = new Image
    book4 = new Image

book1.src = "/llb/assets/book1.jpg"
    book2.src = "/llb/assets/book2.jpg"
book3.src = "/llb/assets/book3.jpg"
    book4.src = "/llb/assets/book4.jpg"
}
function swapImage(thisImage,newImage) {
if (document.images) {
    document[thisImage].src = eval(newImage + ".src")
}
    

}
function show_visibility(IDS){
hide_visibility();
document.getElementById(IDS).style.display = 'block';
}

function hide_visibility(){
var sel = document.getElementById('bookleadin').getElementsByTagName('div');
for (var i=0; i<sel.length; i++) { sel[i].style.display = 'none'; }

}

</script>
</head>

<body>

<div id="content">
   <div id="books">
      <div id="bookimages">
        <img id="bookcover" name="bookcover" src="../llb/assets/book1.jpg" />
        <ul>
          <li><a href="#" onclick="swapImage('bookcover','book1'); show_visibility('bt1'); this.onmouseout=''" onMouseOver="swapImage('bookcover','book1')" onMouseOut="swapImage('bookcover','book1')">1</a></li>
          <li><a href="#" onclick="swapImage('bookcover','book2'); show_visibility('bt2'); this.onmouseout=''" onMouseOver="swapImage('bookcover','book2')" onMouseOut="swapImage('bookcover','book1')">2</a></li>
          <li><a href="#" onclick="show_visibility('bt3'); swapImage('bookcover','book3')" onMouseOver="swapImage('bookcover','book3')" onMouseOut="swapImage('bookcover','book1')" onclick="swapImage('bookcover','book3')">3</a></li>
          <li><a href="#" onclick="show_visibility('bt4'); swapImage('bookcover','book4')" onMouseOver="swapImage('bookcover','book4')" onMouseOut="swapImage('bookcover','book1')" onclick="swapImage('bookcover','book4')">4</a></li>
        </ul>
      </div><!-- end bookimages -->
      <div id="bookleadin">
        <div id="bt1" style="display:block;"><p>Writing starts with living...</p>
      </div>
        <div id="bt2" style="display:none;"><p>The air is silk...</p>
      </div>
        <div id="bt3" style="display:none;"><p>I lived in the woods...</p>
      </div>
        <div id="bt4" style="display:none;"><p>I tried to forget...</p>
      </div>
    </div><!-- end bookleadin -->
    <div class="spacer"></div>
   </div><!-- ends books -->
</div><!-- end content -->

list item #2 is the example I was testing with. I am still a Javascript beginner/intermediate, so any answer has to be simple enough for me to understand and apply to this project or complete so that I can just copy/paste it.

You could set a flag at onclick to be verified if it has been clicked if yes then do the swapping onmouseout else do nothing but do not do this.onmouseout = "".

EDIT:

  <head>
<script>
    if(document.images) {
        book1 = new Image
        book2 = new Image
        book3 = new Image
        book4 = new Image

        book1.src = "/llb/assets/book1.jpg"
        book2.src = "/llb/assets/book2.jpg"
        book3.src = "/llb/assets/book3.jpg"
        book4.src = "/llb/assets/book4.jpg"
    }
    var swap_list = {}; // a list of swapped elements
    function swapImage(thisImage, newImage) {
        if(typeof swap_list[thisImage] == 'undefined' || swap_list[thisImage]=='')
            if(document.images) {
                document[thisImage].src = eval(newImage + ".src");
                swap_list[thisImage] = newImage;
            }
        else
            {
                swap_list[thisImage] = '';
                document[thisImage].src = "../llb/assets/book1.jpg";
            }
    }

    function show_visibility(IDS) {
        hide_visibility();
        document.getElementById(IDS).style.display = 'block';
    }

    function hide_visibility() {
        var sel = document.getElementById('bookleadin').getElementsByTagName('div');
        for(var i = 0; i < sel.length; i++) {
            sel[i].style.display = 'none';
        }

    }
