We consider whether broad absorption line quasars (BAL QSOs) and narrow-line Seyfert 1
galaxies (NLS1s) are similar, as suggested by Brandt & Gallagher and Boroson. For this
purpose, we constructed a sample of 11 BAL QSOs from existing Chandra and Swift
observations. We found that BAL QSOs and NLS1s both operate at high Eddington ratios $
