I haven't had a lot of scrapbook pages published in books and magazines, but I also haven't submitted many for publication either. Back in my early paper scrapbooking days I had fun sending in pages and even had a few get accepted for publication.
Here are some of my previous published layouts:
On page 100 of the December 2007 issue of Digital Scrapbooking (by Simple Scrapbooks). My layout was featured in the "kick it up" section and my tips for making photo collages in picassa were included. This was my first digital layout to ever be published.
Sure Signs of Spring layout published in Memory Makers Celebrating Holidays Scrapbook Style (page 58). Published in 2004 so the book is a little dated but still has fun ideas.
One of my all time favorite projects was this little album I put together for my husband as a Christmas gift. I did the whole thing in under 2 hours while my daughter was at preschool one morning. My hubby still loves this album! Published in Memory Makers Quick and Easy Scrapbook Pages in 2003 on page 112. The book has become a bit dated now but still has a lot of great ideas and they are all very easy and simple!
This might be the publication I am the most proud of because I wrote a feature length article called "Frugal Scrapbooking" that was published on page 44 of Memory Makers January 2003 issue. The main points were to be organized (to avoid duplicate purchases and effectively use the supplies you already have), set a budget and stick to it, shop wisely, use what you have, and remember what is important (the pictures and journaling - not the fancy stickers).
In the September 2001 issue of Memory Makers I had 2 pages featured in the Gathering Place section. These pages featured greeting cards used for a fundraiser for a school for children with autism. My son and the other children pictured were dressed up as angels. All the children had autism so the photo shoot was quite the ordeal - but also a wonderful experience. The cards are no longer available but when they were sold they helped contribute a few thousand dollars to the building of a new school!
I used 58 stickers on a 2 page spread to document my son's favorite things. This is still one of my favorite layouts (and I did a similar spread for my daughter). Published on page 108 of Memory Makers March 2002 issue. (that's not a picture of my son in the article)
I didn't submit any more pages for publication after 2007, although many of my layouts have been featured over at The Daily Digi since then.
I did get the fun surprise of having an older page selected (without me submitting it) to be published in a recent issue of Somerset Digital Art Studio. I have to admit, it's quite thrilling to see something you created in print!
