Up until recently, I was fine with acknowledging that while our students don’t know how to use a print encyclopedia (it’s just sad to watch, really), that searching in our online reference is what they will use mostly now and in the future and that keyword searching is fine for that.
Then while doing an activity with some of my 9th grade history classes that asked them to look in a print encyclopedia I realized that the added research value of a good index is something that is missing from the digital reference we have. For example, if you look for maroons in our Encyclopedia of Latin American History and Culture, the index provides not only the page numbers for for several entries, but also the cross-reference cimarrónes, and the “see also” terms: Palenque, Quilombo, and Miskitos. For the thorough researcher who ventures to those terms in the index as well, they will find valuable information. Under the Miskitos heading is a subheading for “enslavement of African fugitives” that isn’t otherwise referenced in the “maroons” entries, and quilombo leads to subheadings for the specific community of Palmares.
For digital subject encyclopedias in history, we use InfoBase’s History Research Center. Taking my search online, “maroons” yielded 69 results that are encyclopedia entries, with the leading entries being “maroons,” Maroon’s rebellion,” “Maroons in America,” and “Brazilian maroons,” before continuing on with headings that don’t contain the word maroon. None of the 69 results includes the entries for “quilombo,” or “Palmares,” which the print index pointed us to, despite HRC containing articles for both. Throughout this process, there are no suggested terms provided the way you would find indexed terms that cross-reference and nest within larger headings. Reading through the individual articles, you will come across those terms, but they are not flagged, linked, or indicated in association. What HRC does provide is a box with unstructured tag clouds for each entry, and it is unclear how they are determined.
As a side-note, I tried asking ChatGPT for help with the prompt: I’m interested in researching maroons and maroon communities. What are some other terms I should use for searching, beyond “maroon?” ChatGPT provided 20(!) additional terms to search, some of which would be too broad on their own to get me good results (“Creole societies,” “African diaspora,” “guerrilla warfare,” “underground resistance,” and “ethnogenesis”) and some that mirrored the cross-references and subheadings from the print encyclopedia index (“Cimmarones,” and “palenques.”) However, Quilombo, Palmares, and Miskitos did not appear.
Reference sources, to me, require the ability to utilize an index, but indexes are incredibly helpful in other works as well. While Command F and other “search within” search features will find words in your text, these searches can lead to at least 3 less-than-desirable outcomes:
*An over-abundance of results if the term is ubiquitous to your topic,
*A dearth of results because you have the wrong term,
*An incomprehensive set of results because there are places where your topic is discussed but without using the search term.
A good index ameliorates these issues by directing you to the topic where it is discussed in the text regardless of the terms used in that part of the text, as well as providing alternate terms, and where the topic requires nuance, with more specific sub-headings.
To pull back out of the weeds here, a good index provides advantages to a researcher that are distinct from full-text searching. And yet, my 9th graders came in with no idea what an index is, much less how to navigate and leverage them. Convincing them of the nuanced advantages of an index when they are so accustomed to full-text searching may be a challenge. Particularly as I myself was ready to capitulate to the ease of digital reference sources (which I still prefer for their currency in many cases).
My take-away isn’t necessarily that I need to keep print reference works just so students can practice researching with an index. Rather, now that I’m aware of the skill gap and reminded of the important role a good index can play in effective research, I can target my instruction to specifically teach students how to use an index and why they will want that skill. I’ll also bear in mind this gap when working with students on identifying keywords recognizing they may need to work harder at that without the useful suggestions of an index at their pre-research stage. Beyond the instructional elements, I’ve also realized an important piece to look for and advocate for in our digital reference sources so we don’t lose something useful in the translation from print to digital.
