The plastic sheet protectors work best for me, especially when re-sorting or adding songs to the book. To bulky was not a problem, but a blessing in that it caused me to size down my song book(s). It also allows me to have three books, I have yet to need to take all three with me. They are catagorized by style and usually manage reguardless which I take with me.One of the books is my original hand written selections I hav'nt yet put into the PC.
For my preference, I like having three smaller books than carrying a giant. The whole of it is, I'm more organized now than ever in the past.The age of computers has been the largest contributing factor. It's nice to see how we all manage our little lives with sharing information of great importance. We all seem to agree how important our song libraries are.
