Pearl Growing

I know that this post is going to be a bit different than most other this week, because I'm not going to write directly about Henrietta Lacks. Instead, I'm going to write about an information-gathering technique that is much more broadly applied than it would seem in library literature, that of "pearl growing". Now, stick with me, because this actually does apply to Henrietta (or at least to the book). Pearl growing is a term using in reference services for the process of finding a paper applicable to the topic you're researching, looking at the keywords assigned to that paper, and conducting searches based on those new terms. You may only start with one or two words that explain your topic, but through pearl growing, you get a wide vocabulary and a broad base of searchable terms to help you find additional applicable resources.

Now, how does this relate to Henrietta Lacks? Well, I'm taking a bit of artistic license and expanding my definition of pearl growing. If Buckland can classify an antelope as a document (and no, he can't; a document is a VERY strictly prescribed in its sense, as far as this future librarian believes), then I can classify Rebecca Skloot's technique as pearl growing. Skloot goes about gathering information regarding HeLa in a method very similar to that of a reference librarian. A reference librarian may only have books and articles available to him or her to answer the question posed, whereas Skloot is mostly using people and interviews, but nonetheless Skloot uses each interview, telephone call, and medical record as a method for adding words and people to her search. From reading medical records, she gains the names of doctors involved in the medical procedures on Henrietta. From the doctors she finds there, she finds the names of other doctors and the identities of professional organizations concerned with HeLa. Skloot is almost explicit in her use of pearl growing when she talks to the owner of the convenience store in Virginia, who was the proprietor of the to-be HeLa museum and who took her to the cemetery where Henrietta was buried. I don't know that Skloot would describe her technique as pearl growing, but I don't know how we can deny the fact that she adds people and search terms to her repertoire every time she meets another person or reads another person.

So, one may ask the question of why we read the Henrietta Lacks book for LIS 450. Considering that one group in the class is exploring the topic of "One City, One Book", we can certainly argue that we read for similar purposes: reading is a social activity, we glean much experience out of everyone having read the same book. However, I believe that HeLa offers us further insight: the process of interview-based research is not terribly dissimilar [please excuse me, George Orwell, for such an anglophonic (yes, I coined that word) phrase] from that of library research, and we as librarians should keep in mind that the marriage of library and interview-based research can often be quite complementary to one another.
