The Mason OER Metafinder

      Comments Off on The Mason OER Metafinder

2017 12 06 13 22 22I am a relative newcomer to the topic of OERs (Open Educational Resources).  Our Mason Publishing Group—we’re in the same division of the library–has been working with campus groups interested in affordable educational materials for some time now but I haven’t been very involved in those efforts.  Of course, that changed one afternoon this past summer as I grabbed my laptop and tagged along with them to a meeting with the Associate Provost for Undergraduate Education.

As the meeting progressed and moved ever further from my particular areas of expertise, I started stealing moments to jump in and out of various OER content silos–trying to get a better sense of what was already available on the net.   If you’re part of the OER world, you’ll find nothing surprising in my discovery: so many different aggregators of content; so many wildly-different interfaces;  so much duplication; such inconsistent metadata.    I found I was thinking less about OERs and more about how to improve discoverability.

Already familiar with Deep Web Technologies Explorit software (we use it for a number of local search engines like our popular Sciences Metafinder), I realized that discovery of OER materials presents a problem that’s tailor-made for a federated search solution.   Looking across OER sources we find:

  • a large number of search targets (a federated search would save hundreds of clicks),
  • and fortunately each site is more-or-less focused (that’s good, minimizes noise in retrieval sets).
  • We see redundant content across many of these sources (de-duping retrieval would be a huge win, too bad eccentric metadata makes that difficult), and
  • there’s a vertigo-inducing variety of search interfaces (distilling that to one would be great, wouldn’t it?).

Beyond improving the discovery process, I realized building our own search engine would also give us the opportunity to take a more expansive view of what constitutes an OER–by searching the more common OER repositories but also hitting sites that offer quality, open educational content even that isn’t their sole or even primary purpose. Sites like DPLA, HathiTrust (of particular value where the educator belongs to a HathiTrust member institution), Internet Archive, and  World Digital Library to name a few.

I pitched the idea to Deep Web Technologies. Abe Lederman, CEO was very enthusiastic and offered to help us turn the idea around quickly.  True to his word, within just a few weeks we had a powerful OER discovery service ready to go.

I tweeted once or twice about the Metafinder’s existence and shared the link with a few people…but outside Mason we weren’t seeing much interest or activity.  Some weeks later, Deep Web posted a story about the OER Metafinder on their tech blog.   That was picked up by Information Today and other corporate PR news sites and the Metafinder began to build a small audience but still nothing dramatic. I didn’t feel we had failed exactly–the metafinder was impressing local audiences–but I was certainly disappointed. We couldn’t seem to get what I considered a great tool more widely used.

Three or four weeks passed then one morning I saw a message from Abe Lederman in my inbox, subject “OER Metafinder going viral?”   Abe said they had seen a spike, hundreds of hits, on the Metafinder in the past two hours–mostly from the Northeast US.  He asked, “Any idea why?”

I didn’t have a clue but later that afternoon, I got an email mentioning this post on the SPARC Libraries and OER Forum earlier in the day:

I don’t remember seeing this announcement on any of our OER lists last month, or at OpenEd, but one of our library liaisons just forwarded it to me. It’s the announcement of an aggregated OER search engine created by George Mason and a web tech company, which looks, on the face of it, to be a “Google for OER”. It searches many open archival/book repositories (DPLA, HathiTrust, Internet Archive) as well as the standard OER ones (Merlot, OTL, OpenStax, etc.) and has some great limiters to narrow down results. Congrats GMU!

This unsolicited (and favorable) mention on a listserv aimed at precisely the right group of people was catalytic.  Within two days, I searched the LibGuides community site and found 28 institutions already linking to our OER Metafinder.   Seeing it was catching on with LibGuides users, I added search widget code to our “About the Metafinder” page.   As I write this, two weeks after Abe’s initial “gone viral” email, I see more than 85+ sites are linking to us

Three Social Media Library Services

      Comments Off on Three Social Media Library Services

A local library made news in 2010, announcing that it would archive every tweet ever posted.  With Twitter generating 500 million tweets a day, can we really be surprised that it’s proving to be a challenge?

Of course, that doesn’t mean there aren’t a host of smaller services we can build around social media. By way of example, here are three social media services we offer the Mason community. One’s pretty simple while the other two require a bit more infrastructure.

 

Mason Tweets (http://tweet.gmu.edu)

This curated feed from “official” and “near-official” twitter accounts from across the university offers a quick and easy way to take the “Mason Nation” pulse.

To produce this service, we created a MasonTweeter account on Twitter to follow Mason-related feeds.  The web presence is simply a page that embeds the MasonTweeter timeline.

 

 

Preztweets (http://preztweets.gmu.edu)

An archive of every tweet from Mason’s President, Ángel Cabrera.

This service stems from a discussion I had with Dr. Cabrera a few years ago.  At that time, Twitter did not offer users an archive of their tweets (they do now), so we were looking into how we might save his tweets for future university historians.  We settled on a method that offers a searchable database of tweets stored locally in a MySQL database (suitable for future archiving).  Thanks to Andrew M. Whalen for the code that helped build this LAMP-based archiving service.

 

Social Feed Manager (SFM) (https://gwu-libraries.github.io/sfm-ui/

Just the other day, I set up our most ambitious social media service yet: Social Feed Manager.

SFM is a Django application developed by George Washington University Libraries to collect social media data from Twitter. It connects to Twitter’s approved API to collect data in bulk and makes it possible for scholars, students, and librarians to identify, select, collect, and preserve Twitter data for research purposes. We’re running SFM in a Docker container (using Docker for Mac) which simplifies installation and abstracts away much of the underlying complexity.

We have added Social Feed Manager to the suite of data services we offer out of the new Digital Scholarship Center we’ve been shaking down in beta since late January.

wget -> WARC

      Comments Off on wget -> WARC

Had an email exchange yesterday with a group that wants to archive a few of their online web projects in our MARS system. Due to what I hope is a temporary vacancy in our staffing, that meant I had to take the lead in explaining how we handle archiving a website and what the end result of that process looks like.

I had a solid understanding of the what we do part–it’s pretty straightforward: we point a webcrawler at the up-and-running version of the site and pack what we get back into a WARC file. We then upload that WARC file to the DSpace instance that delivers our MARS service and flesh out the metadata. We’ve done a number of these and it works well. My immediate challenge was mastering the how do we do this.

Until recently, the actual work of producing and archiving the WARC file was handled by Jeri Wieringa (who recently moved on from her still-spoken-of-in-reverent-tones stint with our Mason Publishing Group to new challenges). As I started down the WARC-enlightenment path, I was glad to see that our MARS entries for archived sites point the user to WARC-viewing tools for both Windows and MacOS. Seems we recommend Ilya Kreymer’s webarchiveplayer available at https://github.com/ikreymer/webarchiveplayer. So I started there…downloaded and installed the Mac version, pointed it at one of our archived WARC files and in minutes had a pretty firm grasp of this end of the process.

What I still didn’t know was precisely how we had been producing these WARC files. While on Ilya’s GitHub repository for webarchiveplayer I noticed a link to webrecorder—which I later learned corresponds to the service deployed at https://webrecorder.io.   That looks like a large-scale solution and one I’ll set up and test soon. Until then, I’m going with a very lightweight method….wget.

This command from a unix shell or terminal window, produces a useable WARC of this blog:


wget --recursive --warc-file=inodeblog --execute robots=off --domains=inodeblog.com --user-agent=Mozilla http://inodeblog.com

Building the WARC across the net (wget was running on my office iMac at Mason and inodeblog.com lives at reclaim hosting), took roughly 7 minutes. If you’re going to sites you don’t own, you’ll probably want to add a –wait=X switch to pause for ‘X‘ seconds between requests and add your email to your –user-agent= string so people know who to contact if they don’t want to be crawled.

If you wonder how a website looks after it’s been WARC-ed, grab a copy of webarchiveplayer and have a look at the 16 megabyte WARC file for this blog: inodeblog.warc.gz

You can decipher my “switches” and see many other possibilities at this wget documentation site: https://www.gnu.org/software/wget/manual/html_node/index.html#SEC_Contents

I’ll update this post with our “official” method for producing WARCs as soon as I either find a note where Jeri explained our process to me or learn enough to define and document a new standard for us.

A few Library-related RSS feeds

      Comments Off on A few Library-related RSS feeds

Not long ago I started using NetNewsWire once again–shortly after I discovered they’ve finally put across-device-sync back into the rewrite of this long-time favorite RSS reader.  As expected, my back-to-the-future fling with RSS found that many of my go-to feeds had shuttered in the intervening years, but happily many good ones were still around…

It didn’t take me long to rediscover that a decent news reader–and a good set of links–is a great and relatively painless way to stay current.  After a bit of pruning and with a few new additions, I thought it might be useful if I posted my current feed list.   It is a bit idiosyncratic–reflecting my interest in most aspects of digital librarianship.  If you have additions I should know about (and I hope there are many I’m missing), send me a link or better yet, an OPML file of your current feedlist.

about e-content usage…

      Comments Off on about e-content usage…

Was recently asked to help come up with data to help give the library a better handle on who is using our e-resources–to complement the numbers we have on what’s being used.  Hard to be precise given all the variables, but I did hit upon something I think serves as a reasonable proxy (no pun intended).

Step one was to pull together three different datasets:

  • an enormous (70+ million lines) proxy server log that covered all off-campus activity for restricted resources for the entire Fall 2015 semester.  This log has NetIDs for users.
  • our campus directory e-file which includes both a NetID (email address) and the major or departmental affiliation for students, faculty and staff
  • a spreadsheet  from a friend in Admissions which gave meaningful descriptions to the many four letter codes for majors we use here at Mason

The proxy server logs and campus directory were imported into MySQL tables (using the methodology I outlined a couple of years ago in a post about parsing EZProxy logs).  I then ran a simple SQL query:

select affiliation,count(*) from users
join proxy where proxy.username = users.username
group by users.affiliation
order by count(*),desc

Ended up with a result like this:

NURS 3343289
UNDE 2827947
PSYC 2535012
HIST 1536399
CLS 1499991
SOCW 1373797
BIOL 1366712
EDUC 1365084
ACCT 1287198
CRIN 1208750
CS 1203566
GLOA 1131793
COM 1028594
ECON 960981
ENGL 891196
AIT 884840
PUBP 844059

…and so on.

Exported the MySQL results to a CSV file and launched Tableau.  Within Tableau, I joined the results of my MySQL work with the CSV file containing “major codes” and their descriptions (so I could flesh out those NURS, GLOA, PUBP codes).  I hit one of Tableau’s “visualization” buttons.

Got a chart like the excerpt you see below.   Eventually, the complete visualization became an appendix in a document we prepared for internal reporting.  If you’re curious, you can download that final chart as a PDF.

Earlier today I was running a few SQL queries against our local Voyager system–preparing for the upcoming metadata migration to a consortial implementation of Alma.  My tool of choice for this sort of thing is Navicat and as I worked through a series of “count this for me” queries, like…

  • how many bib records have NULL in the NETWORK_NUMBER field?   54,995
  • how many have an OCLC number in that field?  1,640,304
  • exactly how many bib records are there in the database?  3,490,929

…I realized that Navicat made the export of data in a variety of formats a reasonably trivial exercise. Thinking it might be somehow useful for people sharpening their text-mining chops in our new Digital Scholarship Center (2nd floor, Fenwick Library), I decided to build a text file of brief bibliographic data (author, title, publisher, date, etc.) from the 3+ million records in our Voyager database. A simple click in a checkbox produced both JSON and XML versions of the metadata

The zipped versions of these files are roughly 200MB each.

arXiv usage at Mason

      Comments Off on arXiv usage at Mason

The other day we started talking about joining arXiv.org as a way to help support Open Access and the valuable service that arXiv offers.  As you’d expect, the question arose, “How often do we think it’s being used?”

One exploratory email to support at arxiv.org and I had an answer almost within the hour.  For accesses from the gmu.edu domain (meaning the user was on the campus network) we see this activity:

Year    Downloads

2009   2,623

2010   3,867

2011   4,034

2012   4,975

2013   5,821

2014   8,351

2015   8,587

2016  10,480

A steady increase.  Graphed, it’s easy to see.   I’m going to guess that the jump in use around 2013 coincides with our rollout of the Primo discovery service (metadata for arXiv documents is included in the underlying database).

Arxiv gmu

When you consider that we also have users who visit arXiv from off-network devices, it’s an easy decision for us–we are joining arXiv.  Membership fee works out to about 14 cents per download (orders of magnitude better than what we see with Elsevier).

Consortial Borrowing

      Comments Off on Consortial Borrowing

University Libraries belongs to several cooperatives that provide our students, faculty and staff with enhanced access to materials beyond our local print and digital collections.  The big four for Mason are:

LocalWRLC (Washington Research Library Consortium)

StatewideVIVA (Virtual Library of Virginia)

RegionalASERL (Association of Southeastern Research Libraries)

National CRL (Center for Research LIbraries)

A Mason reader can request an item held in the collection of any library affiliated with one of these cooperatives and its delivery will be expedited thanks to something rather akin to the “favored nation” status that exists between members of each collective.

As you might guess, thanks to ease of networked discovery and physical resource proximity, researchers at Mason borrow a fair amount of material from fellow member institutions in the WRLC.   What might surprise you is that Mason is a net lender to our fellow WRLC institutions (e.g., they borrow more from us than we borrow from them) and we have a similar status with the ASERL membership as well.  I view this as marker of the strength and currency of Mason’s collections…though I know the danger of basing an argument  on data viewed in isolation (e.g., a contrarian might argue that the collections of others are equally strong and also heavily used and we’re just racking up lending numbers as the backup source for that 2nd or 3rd copy of something).  “Data-informed” is safer than “data-driven.”

Wondering how that activity is distributed across potential users and our collections, I decided to generate a “snapshot” dataset of every item currently checked-out to an affiliate of WRLC.  Then I graphed the level of ‘borrowing-from-Mason’ activity by staff, undergraduate, graduate and faculty users at each member library (click to enlarge the graphic):

Wrlc Borrowing

WRLC Borrowing from Mason by School and Borrower Status

Graduate students at George Washington are our most active borrowers (with 115 items in circulation).  Seems odd but GW faculty are tied with an identical 115 items charged at the moment.  As you move down the left column, you find AU faculty coming in third with 89 items, followed by Georgetown graduate students at 87, and so on down the list.

What sections of our library collection most interest WRLC borrowers?  The next graph shows by Call Number stem just how many items are currently in circulation to various WRLC borrowers.   The PR classification (English Literature) leads the list with 160+ items. QA (Mathematics…but you’ll find most of the computer books carry a QA classification as well) comes in a close second.  Love the fact that Z (Library Science and Bibliography) trails the list  🙂

A few Primo numbers…

      Comments Off on A few Primo numbers…

2016 04 05 12 02 38

A few observations based on 12 months of data from our Primo discovery system (Jan 2015 ~ Dec 2015):

Sessions:

  •  333,091 unique sessions
  •  Roughly 2% originated outside the U.S.
  • Users signed in 5382 times (roughly 1.5% of sessions)

Great to see there were 333K sessions during the year but the fact that fewer than 2% of our users ever sign in is particularly worrisome for a library that serves a geographically-dispersed community. A number of our content providers require that their material be excluded from discovery and delivery if you can’t show that you have a Mason affiliation. Working from a device on the campus network meets that test for most of these vendors but a signon with our Primo satisfies them all.

So, whether you’re studying in a local coffeeshop before your evening class, or you are a Mason Online student hundreds of miles from campus, to search Primo for content from ARTstor, MLA International Bibliography,  Web of Science and several other resources  you’ll have to sign in.

2016-04-05_12-28-54

Worth mentioning a few other benefits that signing-on delivers:

– tweak the relevance of Primo’s retrieval–ranking materials in your area of interest more highly

– store items on your personal e-shelf between Primo sessions

– increase the number of results per page (up to 50)

– access your circulation record

– set up recurring queries

– build RSS feeds of result sets

…and more

Searches:

  • 1.1 million searches were performed
  • 999,731 of those were basic searches (90.3%)
  • 106,314 were advanced searches
