“…A number of researchers have investigated the effects of scrolling versus paging in the comprehension and retention of material (see, e.g., Schwartz, Beldie and Pastoor, 1983); the differences in anaphoric resolution, (that is, the ability of readers to make recursive switches to preceeding text material), and its effects on retrieval and reader recollection, (see, e.g., Muter, Latremouille, Treurniet and Beam, 1982;Muter and Maurutto, 1991;Wright, 1987;Lovelace and Southall, 1983); and finally, the lack of portability (that is the ability to carry the medium around in physical space like a book) and annotation capabilities in this medium (that is the ability to directly label and mark texts) (see, e.g., Wright and Lickorish, 1984). What is fascinating is that even on this list, a number of idiosyncratic conventions such as the use of capital letters, and asterisks bounding a word serve to annotate texts for readers.…”
