Source Publication (e.g., journal title)
PRINT STILL PREDOMINATES in journal publishing, but that role may soon fade. Too slowly or too quickly, steadily or in fits and starts (depending on your perspective and patience level), scholarly journals are moving toward reliance on digital forms. This is happening in part because librarians, scholars, and even some publishers are unhappy about the current state of print journals.
