How to Dig Up Family History Online

J.D. Biersdorfer. "How to Dig Up Family History Online." New York Times. June 25, 2020, p. B7.

While not all government records may be free or digitized, the National Archives hosts a page of links from other genealogy sites where you can look for information.

... 
Libraries and historical/genealogical societies may also have books and periodicals that recorded the development of the area and the people who lived there, although you may have to visit in person to look at the original material has not been scanned. (Some libraries also offer free access to the commercial genealogy services.)

COMMENT 

     The article mentions online genealogy sites and the National Archives as places to start.  Libraries come in further down the list once you have done your background research online. They type of local history that genealogists seek can be hard to find. There is a period when newspapers were preserved on microfilm, and many of these have never been digitized. One-of-a-kind Special Collections materials are hidden treasure in dusty boxes.  If you get a chance to poke through them, you might find something fascinating.

How to Read Coronavirus Studies Like a Scientist

Carl Zimmer, "How to Read Coronavirus Studies Like a Scientist." New York Times, Jun 2, 2020, p. D7.

     The National Library of Medicine's Database at the start of June contains over 17,000 published papers about he new coronavirus.  A website called bioRxiv, which hosts studies that have yet to go through peer review, contains over 4,000 papers.
     In earlier times, few people aside from scientists would have laid eyes on these papers.  Months or years after they were written, they'd wind up in printed journals tucked away on a library shelf.  But now the world can surf the rising tide of research on the new coronavirus. The vast majority of papers about it can be read free online.
     But just because scientific papers are easier to get hold of doesn't mean that they are easier to make sense of.  Reading them can be a challenge for the layperson, even one with some science education.  It's not just the jargon that scientists use to compress a lot of results into a small space. Just like sonnets, sagas and short stories, scientific papers are a genre with its own unwritten rules, rules that have developed over generations. 
COMMENT

   This article offers a variation of the library "dusty shelves" with unread articles tucked away until they were rescued by online distribution. Many publishers have made COVID-19 studies open-access, but in fact there are usually paywalls between laypeople and scientific journal  literature.   The article offers helpful advice for how to approach scientific literature.  The article mentions NLM databases and a medical pre-print archive.  Medical information has its own unique information system because it can be so urgent for doctors and public health agencies to have up-to-date research.

University Contributions to the Circular Economy

Nunes, Ben, et al. "University Contributions to the Circular Economy: Professing the Hidden Curriculum." Sustainability10.8 (2018): 2719-


Scopus was used to identify 150 pieces of relevant literature. These were then reduced to 70 studies by only including (i) papers appearing in journals with an impact factor cited by the Web of Science, (ii) books receiving a high level of citation on Google Scholar, and (iii) publications relevant to the topic of study.[p.2718]

 COMMENT

   Scholarly articles nearly always have a literature review, but the library research process is almost always invisible. It's just assumed that scholars know how to use the library.  In this paper, the researchers used an expensive research database called Scopus which was almost certainly provided by an unmentioned academic library. The process of winnowing such papers is described.   The authors specifically threw out papers that are not published in peer reviewed journals or scholarly books.  This research strategy is good as far as it goes, but it has the potential to create a blind spot. University facilities are often managed by people who are not faculty and who therefore have no mandate to write publish. As a result, it is harder to find papers about faculties management than articles about university curriculum and teaching. If I were advising these researchers  I might have suggested extending the Scopus search with citation searches on the key articles as well as reviewing the article bibliographies for relevant publications. I also might have suggested seeking out reports published by universities that were not published in journals at all.

It's a Dog's World in the Lab

James Gorman. “It’s a Dog’s World in the Lab: When it Comes to Research, Scientists Favor Canines Over Cats by a Large Margin.” New York Times, December 30, 2018 p.F14 [Originally Published Feb. 26]

And now the numbers: A search of Pub Med, a database that include most biomedical journals, yielded 139,858 results for cats and 2,850,000 for dogs.  These are sample searches, of course, and don't say much about the kind of research that was undertaken. As for journalism, my searches on the news database Nexis for dogs and cats kept returning more than 3,000 hits, which my screen warned my would take a long time to retrieve.  So I settled for searches of “dog genome” and “cat genome.” The result, 20 for dogs, 6 for cats.  The dog genome was sequenced before the cat genome.      I would caution against concluding anything based on this haphazard browsing other than the results do back up the researchers’ sense that there’s more research on dogs. 
COMMENT

      Journal databases provide a quick and dirty estimate of the relative number of scientific studies.  The researcher used Pub Med for scholarly journals and Nexis for news, two databases that most librarians would be familiar with. One assumes that the author was a savvy enough searcher to realize that the letters "CAT" and "DOG" don't always mean felines and canines.

   The author does not actually say whether these databases were from a library or not.  Pub Med is a service of the National Library of Medicine, though, so it's technically a library regardless. Nexis is an expensive subscription so a library is the most likely point of access.

     When people search online databases they often miss the fact that they are a library service.  Scholars at universities sometimes claim that they never use the library because they can find all the articles they need online.  These researchers don't realize that the library has paid for their access or that convenient links to articles from Google Scholar are thanks to library software that integrates database subscriptions into the search.

A more formal version of this kind of citation analysis is frequently used in bibliometric studies to trace the development of scholarship-- say the use of the word "Sustainability" after the publication of the Brundtland Report, [1] or the rise of the word "Anthopocene" as a metaphor for human influence on the Earth.
