Since our school has been phasing in our 1:1 program, there's been a push to utilize online texts to lighten the backpacks of the girls. I remember making calls to religion text publishers a couple of years ago asking about online texts or versions on CD-rom. Not much going on then. Resources available on publishers' websites but not actual texts in our discipline.
That's changed now. I know of two publishers who are either making books available in an electronic format or are at least thinking about it. Today I filled out a survey for one company about just that topic. Another sent me an e-mail offering a review copy of a text that could be delivered either through UPS or electronically.
The times they are a changin'.
