Me too MD. A new Church was just built about 200 yards from my place of work and its always open when I punch out!! And I usually go in with Bible (big Douay Rheims) in hand or pocket (little King James Version New Testament with Psalms and Proverbs) to read.
When I think about going in without my Bible I hear Bp. Sheen's voice ringing in my ears "Always, always the Scriptures!", words he spoke when he talked about how to make a Holy Hour in front of the Blessed Sacrament. He left room for just about anything during it, but the Scriptures should always be included.
Freegards.
Have you considered an iPhone? I have the entire Bible (complete with a boolian search feature), Catholic calendar with daily readings, a compendium of prayers, the Stations of the Cross, the Rosary, etc. in an app called iPieta. It’s fabulous. I still use a missal at Mass though because when I’m using the phone people might think I’m just checking my messages or something!
