Print vs. Electronic
Which to teach?

Why teach both?

Need to know some basics about the printed product to use the electronic product well.

Some print tools strongly influence their electronic counterparts.

Chemical Abstracts - abbreviations, inverted subject headings

Science Citation Index - citations by first author only

Don't teach what you don't own.

Exception: for graduate students and upper-division undergraduates, you may want to at least mention tools which they'll find elsewhere.

Points Worth Pondering

Some print tools are easy to use and their electronic counterparts difficult (or expensive)
Start with the quickest, easiest tools and build up to the more difficult but more powerful.

Some print tools have different coverage than their electronic counterparts
Chronological range - usually print goes back farther
Currency of information - usually, electronic has the edge, but not always with CD-ROM.
